For (E)MRS BA[2:0] selects an (Extended) Mode Register. 6) VREF must be maintained during Self Refresh operation. 7) Self Refresh Exit is asynchronous. 8) Burst reads or writes at BL = 4 cannot be terminated. 9) The Power Down Mode does not perform any refresh operations. The duration of Power Down is therefore limited by the refresh requirements.

Command (N) is the command registered at clock edge N, and Action (N) is a result of Command (N) The state of ODT does not affect the states described in this table. The ODT function is not available during Self Refresh. CKE must be maintained HIGH while the device is in OCD calibration mode. Operation that is not specified is illegal and after such an event, in order to guarantee proper operation, the DRAM must be powered down and then restarted through the specified initialization sequence before normal operation can continue. CKE (N) is the logic state of CKE at clock edge N; CKE (N-1) was the state of CKE at the previous clock edge. The Power-Down Mode does not perform any refresh operations. The duration of Power-Down Mode is therefor limited by the refresh requirements “X” means “don’t care (including floating around VREF)” in Self Refresh and Power Down. However ODT must be driven HIGH or LOW in Power Down if the ODT function is enabled (Bit A2 or A6 set to “1” in EMRS(1)). All states and sequences not shown are illegal or reserved unless explicitly described elsewhere in this document. Valid commands for Power-Down Entry and Exit are NOP and DESELECT only. tCKE.MIN of 3 clocks means CKE must be registered on three consecutive positive clock edges. CKE must remain at the valid input level the entire time it takes to achieve the 3 clocks of registration. Thus, after any CKE transition, CKE may not transition from its valid level during the time period of tIS + 2 × tCK + tIH. VREF must be maintained during Self Refresh operation. On Self Refresh Exit DESELECT or NOP commands must be issued on every clock edge occurring during the tXSNR period. Read commands may be issued only after tXSRD (200 clocks) is satisfied. Valid commands for Self Refresh Exit are NOP and DESELCT only. Power-Down and Self Refresh can not be entered while Read or Write operations, (Extended) mode Register operations, Precharge or Refresh operations are in progress. Self Refresh mode can only be entered from the All Banks Idle state. Must be a legal command as defined in the Command Truth Table.

The method by which the DDR2 SDRAM pin timing are measured is mode dependent. In single ended mode, timing relationships are measured relative to the rising or falling edges of DQS crossing at VREF. In differential mode, these timing relationships are measured relative to the crosspoint of DQS and its complement, DQS. This distinction in timing methods is verified by design and characterization but not subject to production test. In single ended mode, the DQS (and RDQS) signals are internally disabled and don’t care.

The SSTL_18 test load has a 20 Ohm series resistor additionally to the 25 Ohm termination resistor into VTT. The SSTL_18 definition assumes that ± 335 mV must be developed across the effectively 25 Ohm termination resistor (13.4 mA × 25 Ohm = 335 mV). With an additional series resistor of 20 Ohm this translates into a minimum requirement of 603 mV swing relative to VTT, at the ouput device (13.4 mA × 45 Ohm = 603 mV).

For DQS signals timings are guaranteed with a differential Slew Rate of 2.0 V/ns in differential strobe mode and a Slew Rate of 1 V/ns in single ended mode. 4) The CK / CK input reference level (for timing reference to CK / CK) is the point at which CK and CK cross. The DQS / DQS, RDQS / RDQS, input reference level is the crosspoint when in differential strobe mode. The input reference level for signals other than CK/CK, DQS/DQS, RDQS / RDQS is defined. 5) Inputs are not recognized as valid until VREF stabilizes. During the period before VREF stabilizes, CKE = 0.2 x VDDQ is recognized as low. 6) The output timing reference voltage level is VTT. 7) New units, ‘tCK.AVG‘ and ‘nCK‘, are introduced in DDR2–667 and DDR2–800. Unit ‘tCK.AVG‘ represents the actual tCK.AVG of the input clock under operation. Unit ‘nCK‘ represents one clock cycle of the input clock, counting the actual clock edges. Note that in DDR2–400 and DDR2–533, ‘tCK‘ is used for both concepts. Example: tXP = 2 [nCK] means; if Power Down exit is registered at Tm, an Active command may be registered at Tm + 2, even if (Tm + 2 - Tm) is 2 x tCK.AVG + tERR.2PER(Min). 8) When the device is operated with input clock jitter, this parameter needs to be derated by the actual tERR(6-10per) of the input clock. (output deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR2–667 SDRAM has tERR(6-10PER).MIN = – 272 ps and tERR(6- 10PER).MAX = + 293 ps, then tDQSCK.MIN(DERATED) = tDQSCK.MIN – tERR(6-10PER).MAX = – 400 ps – 293 ps = – 693 ps and tDQSCK.MAX(DERATED) = tDQSCK.MAX – tERR(6-10PER).MIN = 400 ps + 272 ps = + 672 ps. Similarly, tLZ.DQ for DDR2–667 derates to tLZ.DQ.MIN(DERATED) = - 900 ps – 293 ps = – 1193 ps and tLZ.DQ.MAX(DERATED) = 450 ps + 272 ps = + 722 ps. (Caution on the MIN/MAX usage!) 9) Input clock jitter spec parameter. These parameters and the ones in Chapter 7.3 are referred to as 'input clock jitter spec parameters' and these parameters apply to DDR2–667 and DDR2–800 only. The jitter specified is a random jitter meeting a Gaussian distribution. Rev. 1.3, 2007-07 03062006-ZNH8-HURV 49 Internet Data Sheet HY[B/I]18T1G[40/80/16]0B[C/F](L/V) 1-Gbit Double-Data-Rate-Two SDRAM 10) These parameters are specified per their average values, however it is understood that the relationship as defined in Chapter 7.3 between the average timing and the absolute instantaneous timing holds all the times (min. and max of SPEC values are to be used for calculations of Chapter 7.3). 11) tCKE.MIN of 3 clocks means CKE must be registered on three consecutive positive clock edges. CKE must remain at the valid input level the entire time it takes to achieve the 3 clocks of registration. Thus, after any CKE transition, CKE may not transition from its valid level during the time period of tIS + 2 x tCK + tIH. 12) DAL = WR + RU{tRP(ns) / tCK(ns)}, where RU stands for round up. WR refers to the tWR parameter stored in the MRS. For tRP, if the result of the division is not already an integer, round up to the next highest integer. tCK refers to the application clock period. Example: For DDR2–533 at tCK = 3.75 ns with tWR programmed to 4 clocks. tDAL = 4 + (15 ns / 3.75 ns) clocks = 4 + (4) clocks = 8 clocks. 13) tDAL.nCK = WR [nCK] + tnRP.nCK = WR + RU{tRP [ps] / tCK.AVG[ps] }, where WR is the value programmed in the EMR. 14) Input waveform timing tDH with differential data strobe enabled MR[bit10] = 0, is referenced from the differential data strobe crosspoint to the input signal crossing at the VIH.DC level for a falling signal and from the differential data strobe crosspoint to the input signal crossing at the VIL.DC level for a rising signal applied to the device under test. DQS, DQS signals must be monotonic between VIL.DC.MAX and VIH.DC.MIN. See Figure 9. 15) tDQSQ: Consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers as well as output slew rate mismatch between DQS / DQS and associated DQ in any given cycle. 16) These parameters are measured from a data strobe signal ((L/U/R)DQS / DQS) crossing to its respective clock signal (CK / CK) crossing. The spec values are not affected by the amount of clock jitter applied (i.e. tJIT.PER, tJIT.CC, etc.), as these are relative to the clock signal crossing. That is, these parameters should be met whether clock jitter is present or not. 17) Input waveform timing tDS with differential data strobe enabled MR[bit10] = 0, is referenced from the input signal crossing at the VIH.AC level to the differential data strobe crosspoint for a rising signal, and from the input signal crossing at the VIL.AC level to the differential data strobe crosspoint for a falling signal applied to the device under test. DQS, DQS signals must be monotonic between Vil(DC)MAX and Vih(DC)MIN. See Figure 9. 18) If tDS or tDH is violated, data corruption may occur and the data must be re-written with valid data before a valid READ can be executed. 19) These parameters are measured from a data signal ((L/U)DM, (L/U)DQ0, (L/U)DQ1, etc.) transition edge to its respective data strobe signal ((L/U/R)DQS / DQS) crossing. 20) tHP is the minimum of the absolute half period of the actual input clock. tHP is an input parameter but not an input specification parameter. It is used in conjunction with tQHS to derive the DRAM output timing tQH. The value to be used for tQH calculation is determined by the following equation; tHP = MIN (tCH.ABS, tCL.ABS), where, tCH.ABS is the minimum of the actual instantaneous clock high time; tCL.ABS is the minimum of the actual instantaneous clock low time. 21) tHZ and tLZ transitions occur in the same access time as valid data transitions. These parameters are referenced to a specific voltage level which specifies when the device output is no longer driving (tHZ), or begins driving (tLZ) . 22) Input waveform timing is referenced from the input signal crossing at the VIL.DC level for a rising signal and VIH.DC for a falling signal applied to the device under test. See Figure 10. 23) Input waveform timing is referenced from the input signal crossing at the VIH.AC level for a rising signal and VIL.AC for a falling signal applied to the device under test. See Figure 10. 24) These parameters are measured from a command/address signal (CKE, CS, RAS, CAS, WE, ODT, BA0, A0, A1, etc.) transition edge to its respective clock signal (CK / CK) crossing. The spec values are not affected by the amount of clock jitter applied (i.e. tJIT.PER, tJIT.CC, etc.), as the setup and hold are relative to the clock signal crossing that latches the command/address. That is, these parameters should be met whether clock jitter is present or not. 25) tQH = tHP – tQHS, where: tHP is the minimum of the absolute half period of the actual input clock; and tQHS is the specification value under the max column. {The less half-pulse width distortion present, the larger the tQH value is; and the larger the valid data eye will be.} Examples: 1) If the system provides tHP of 1315 ps into a DDR2–667 SDRAM, the DRAM provides tQH of 975 ps minimum. 2) If the system provides tHP of 1420 ps into a DDR2–667 SDRAM, the DRAM provides tQH of 1080 ps minimum. 26) tQHS accounts for: 1) The pulse duration distortion of on-chip clock circuits, which represents how well the actual tHP at the input is transferred to the output; and 2) The worst case push-out of DQS on one transition followed by the worst case pull-in of DQ on the next transition, both of which are independent of each other, due to data pin skew, output pattern effects, and pchannel to n-channel variation of the output drivers. 27) The Auto-Refresh command interval has be reduced to 3.9 µs when operating the DDR2 DRAM in a temperature range between 85 °C and 95 °C. 28) 0 °C≤ TCASE ≤ 85 °C 29) 85 °C < TCASE ≤ 95 °C 30) A maximum of eight Auto-Refresh commands can be posted to any given DDR2 SDRAM device. 31) tRPST end point and tRPRE begin point are not referenced to a specific voltage level but specify when the device output is no longer driving (tRPST), or begins driving (tRPRE). Figure 8 shows a method to calculate these points when the device is no longer driving (tRPST), or begins driving (tRPRE) by measuring the signal at two different voltages. The actual voltage measurement points are not critical as long as the calculation is consistent. Rev. 1.3, 2007-07 03062006-ZNH8-HURV 50 Internet Data Sheet HY[B/I]18T1G[40/80/16]0B[C/F](L/V) 1-Gbit Double-Data-Rate-Two SDRAM 32) When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJIT.PER of the input clock. (output deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR2–667 SDRAM has tJIT.PER.MIN = – 72 ps and tJIT.PER.MAX = + 93 ps, then tRPRE.MIN(DERATED) = tRPRE.MIN + tJIT.PER.MIN = 0.9 x tCK.AVG – 72 ps = + 2178 ps and tRPRE.MAX(DERATED) = tRPRE.MAX + tJIT.PER.MAX = 1.1 x tCK.AVG + 93 ps = + 2843 ps. (Caution on the MIN/MAX usage!). 33) When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJIT.DUTY of the input clock. (output deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR2–667 SDRAM has tJIT.DUTY.MIN = – 72 ps and tJIT.DUTY.MAX = + 93 ps, then tRPST.MIN(DERATED) = tRPST.MIN + tJIT.DUTY.MIN = 0.4 x tCK.AVG – 72 ps = + 928 ps and tRPST.MAX(DERATED) = tRPST.MAX + tJIT.DUTY.MAX = 0.6 x tCK.AVG + 93 ps = + 1592 ps. (Caution on the MIN/MAX usage!). 34) For these parameters, the DDR2 SDRAM device is characterized and verified to support tnPARAM = RU{tPARAM / tCK.AVG}, which is in clock cycles, assuming all input clock jitter specifications are satisfied. For example, the device will support tnRP = RU{tRP / tCK.AVG}, which is in clock cycles, if all input clock jitter specifications are met. This means: For DDR2–667 5–5–5, of which tRP = 15 ns, the device will support tnRP = RU{tRP / tCK.AVG} = 5, i.e. as long as the input clock jitter specifications are met, Precharge command at Tm and Active command at Tm + 5 is valid even if (Tm + 5 - Tm) is less than 15 ns due to input clock jitter. 35) tWTR is at lease two clocks (2 x tCK) independent of operation frequency.

For DQS signals timings are guaranteed with a differential Slew Rate of 2.0 V/ns in differential strobe mode and a Slew Rate of 1 V/ns in single ended mode. 4) The CK / CK input reference level (for timing reference to CK / CK) is the point at which CK and CK cross. The DQS / DQS, RDQS / RDQS, input reference level is the crosspoint when in differential strobe mode. The input reference level for signals other than CK/CK, DQS/DQS, RDQS / RDQS is defined. 5) Inputs are not recognized as valid until VREF stabilizes. During the period before VREF stabilizes, CKE = 0.2 x VDDQ is recognized as low. 6) The output timing reference voltage level is VTT. Rev. 1.3, 2007-07 03062006-ZNH8-HURV 52 Internet Data Sheet HY[B/I]18T1G[40/80/16]0B[C/F](L/V) 1-Gbit Double-Data-Rate-Two SDRAM 7) New units, ‘tCK.AVG‘ and ‘nCK‘, are introduced in DDR2–667 and DDR2–800. Unit ‘tCK.AVG‘ represents the actual tCK.AVG of the input clock under operation. Unit ‘nCK‘ represents one clock cycle of the input clock, counting the actual clock edges. Note that in DDR2–400 and DDR2–533, ‘tCK‘ is used for both concepts. Example: tXP = 2 [nCK] means; if Power Down exit is registered at Tm, an Active command may be registered at Tm + 2, even if (Tm + 2 - Tm) is 2 x tCK.AVG + tERR.2PER(Min). 8) When the device is operated with input clock jitter, this parameter needs to be derated by the actual tERR(6-10per) of the input clock. (output deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR2–667 SDRAM has tERR(6-10PER).MIN = – 272 ps and tERR(6- 10PER).MAX = + 293 ps, then tDQSCK.MIN(DERATED) = tDQSCK.MIN – tERR(6-10PER).MAX = – 400 ps – 293 ps = – 693 ps and tDQSCK.MAX(DERATED) = tDQSCK.MAX – tERR(6-10PER).MIN = 400 ps + 272 ps = + 672 ps. Similarly, tLZ.DQ for DDR2–667 derates to tLZ.DQ.MIN(DERATED) = - 900 ps – 293 ps = – 1193 ps and tLZ.DQ.MAX(DERATED) = 450 ps + 272 ps = + 722 ps. (Caution on the MIN/MAX usage!) 9) Input clock jitter spec parameter. These parameters and the ones in Chapter 7.3 are referred to as 'input clock jitter spec parameters' and these parameters apply to DDR2–667 and DDR2–800 only. The jitter specified is a random jitter meeting a Gaussian distribution. 10) These parameters are specified per their average values, however it is understood that the relationship as defined in Chapter 7.3 between the average timing and the absolute instantaneous timing holds all the times (min. and max of SPEC values are to be used for calculations of Chapter 7.3). 11) tCKE.MIN of 3 clocks means CKE must be registered on three consecutive positive clock edges. CKE must remain at the valid input level the entire time it takes to achieve the 3 clocks of registration. Thus, after any CKE transition, CKE may not transition from its valid level during the time period of tIS + 2 x tCK + tIH. 12) DAL = WR + RU{tRP(ns) / tCK(ns)}, where RU stands for round up. WR refers to the tWR parameter stored in the MRS. For tRP, if the result of the division is not already an integer, round up to the next highest integer. tCK refers to the application clock period. Example: For DDR2–533 at tCK = 3.75 ns with tWR programmed to 4 clocks. tDAL = 4 + (15 ns / 3.75 ns) clocks = 4 + (4) clocks = 8 clocks. 13) tDAL.nCK = WR [nCK] + tnRP.nCK = WR + RU{tRP [ps] / tCK.AVG[ps] }, where WR is the value programmed in the EMR. 14) Input waveform timing tDH with differential data strobe enabled MR[bit10] = 0, is referenced from the differential data strobe crosspoint to the input signal crossing at the VIH.DC level for a falling signal and from the differential data strobe crosspoint to the input signal crossing at the VIL.DC level for a rising signal applied to the device under test. DQS, DQS signals must be monotonic between VIL.DC.MAX and VIH.DC.MIN. See Figure 9. 15) tDQSQ: Consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers as well as output slew rate mismatch between DQS / DQS and associated DQ in any given cycle. 16) These parameters are measured from a data strobe signal ((L/U/R)DQS / DQS) crossing to its respective clock signal (CK / CK) crossing. The spec values are not affected by the amount of clock jitter applied (i.e. tJIT.PER, tJIT.CC, etc.), as these are relative to the clock signal crossing. That is, these parameters should be met whether clock jitter is present or not. 17) Input waveform timing tDS with differential data strobe enabled MR[bit10] = 0, is referenced from the input signal crossing at the VIH.AC level to the differential data strobe crosspoint for a rising signal, and from the input signal crossing at the VIL.AC level to the differential data strobe crosspoint for a falling signal applied to the device under test. DQS, DQS signals must be monotonic between Vil(DC)MAX and Vih(DC)MIN. See Figure 9. 18) If tDS or tDH is violated, data corruption may occur and the data must be re-written with valid data before a valid READ can be executed. 19) These parameters are measured from a data signal ((L/U)DM, (L/U)DQ0, (L/U)DQ1, etc.) transition edge to its respective data strobe signal ((L/U/R)DQS / DQS) crossing. 20) tHP is the minimum of the absolute half period of the actual input clock. tHP is an input parameter but not an input specification parameter. It is used in conjunction with tQHS to derive the DRAM output timing tQH. The value to be used for tQH calculation is determined by the following equation; tHP = MIN (tCH.ABS, tCL.ABS), where, tCH.ABS is the minimum of the actual instantaneous clock high time; tCL.ABS is the minimum of the actual instantaneous clock low time. 21) tHZ and tLZ transitions occur in the same access time as valid data transitions. These parameters are referenced to a specific voltage level which specifies when the device output is no longer driving (tHZ), or begins driving (tLZ) . 22) Input waveform timing is referenced from the input signal crossing at the VIL.DC level for a rising signal and VIH.DC for a falling signal applied to the device under test. See Figure 10. 23) Input waveform timing is referenced from the input signal crossing at the VIH.AC level for a rising signal and VIL.AC for a falling signal applied to the device under test. See Figure 10. 24) These parameters are measured from a command/address signal (CKE, CS, RAS, CAS, WE, ODT, BA0, A0, A1, etc.) transition edge to its respective clock signal (CK / CK) crossing. The spec values are not affected by the amount of clock jitter applied (i.e. tJIT.PER, tJIT.CC, etc.), as the setup and hold are relative to the clock signal crossing that latches the command/address. That is, these parameters should be met whether clock jitter is present or not. 25) tQH = tHP – tQHS, where: tHP is the minimum of the absolute half period of the actual input clock; and tQHS is the specification value under the max column. {The less half-pulse width distortion present, the larger the tQH value is; and the larger the valid data eye will be.} Examples: 1) If the system provides tHP of 1315 ps into a DDR2–667 SDRAM, the DRAM provides tQH of 975 ps minimum. 2) If the system provides tHP of 1420 ps into a DDR2–667 SDRAM, the DRAM provides tQH of 1080 ps minimum. Rev. 1.3, 2007-07 03062006-ZNH8-HURV 53 Internet Data Sheet HY[B/I]18T1G[40/80/16]0B[C/F](L/V) 1-Gbit Double-Data-Rate-Two SDRAM 26) tQHS accounts for: 1) The pulse duration distortion of on-chip clock circuits, which represents how well the actual tHP at the input is transferred to the output; and 2) The worst case push-out of DQS on one transition followed by the worst case pull-in of DQ on the next transition, both of which are independent of each other, due to data pin skew, output pattern effects, and pchannel to n-channel variation of the output drivers. 27) The Auto-Refresh command interval has be reduced to 3.9 µs when operating the DDR2 DRAM in a temperature range between 85 °C and 95 °C. 28) 0 °C≤ TCASE ≤ 85 °C 29) 85 °C < TCASE ≤ 95 °C 30) A maximum of eight Auto-Refresh commands can be posted to any given DDR2 SDRAM device. 31) tRPST end point and tRPRE begin point are not referenced to a specific voltage level but specify when the device output is no longer driving (tRPST), or begins driving (tRPRE). Figure 8 shows a method to calculate these points when the device is no longer driving (tRPST), or begins driving (tRPRE) by measuring the signal at two different voltages. The actual voltage measurement points are not critical as long as the calculation is consistent. 32) When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJIT.PER of the input clock. (output deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR2–667 SDRAM has tJIT.PER.MIN = – 72 ps and tJIT.PER.MAX = + 93 ps, then tRPRE.MIN(DERATED) = tRPRE.MIN + tJIT.PER.MIN = 0.9 x tCK.AVG – 72 ps = + 2178 ps and tRPRE.MAX(DERATED) = tRPRE.MAX + tJIT.PER.MAX = 1.1 x tCK.AVG + 93 ps = + 2843 ps. (Caution on the MIN/MAX usage!). 33) When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJIT.DUTY of the input clock. (output deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR2–667 SDRAM has tJIT.DUTY.MIN = – 72 ps and tJIT.DUTY.MAX = + 93 ps, then tRPST.MIN(DERATED) = tRPST.MIN + tJIT.DUTY.MIN = 0.4 x tCK.AVG – 72 ps = + 928 ps and tRPST.MAX(DERATED) = tRPST.MAX + tJIT.DUTY.MAX = 0.6 x tCK.AVG + 93 ps = + 1592 ps. (Caution on the MIN/MAX usage!). 34) For these parameters, the DDR2 SDRAM device is characterized and verified to support tnPARAM = RU{tPARAM / tCK.AVG}, which is in clock cycles, assuming all input clock jitter specifications are satisfied. For example, the device will support tnRP = RU{tRP / tCK.AVG}, which is in clock cycles, if all input clock jitter specifications are met. This means: For DDR2–667 5–5–5, of which tRP = 15 ns, the device will support tnRP = RU{tRP / tCK.AVG} = 5, i.e. as long as the input clock jitter specifications are met, Precharge command at Tm and Active command at Tm + 5 is valid even if (Tm + 5 - Tm) is less than 15 ns due to input clock jitter. 35) tWTR is at lease two clocks (2 x tCK) independent of operation frequency.

See Table 5 “Ordering Information for Lead-Free Products (RoHS Compliant)” on Page 5. 18) The maximum limit for the tWPST parameter is not a device limit. The device operates with a greater value for this parameter, but system performance (bus turnaround) degrades accordingly. 19) Minimum tWTR is two clocks when operating the DDR2-SDRAM at frequencies ≤ 200 ΜΗz. 20) User can choose two different active power-down modes for additional power saving via MRS address bit A12. In “standard active powerdown mode” (MR, A12 = “0”) a fast power-down exit timing tXARD can be used. In “low active power-down mode” (MR, A12 =”1”) a slow power-down exit timing tXARDS has to be satisfied. 21) WR must be programmed to fulfill the minimum requirement for the tWR timing parameter, where WRMIN[cycles] = tWR(ns)/tCK(ns) rounded up to the next integer value. tDAL = WR + (tRP/tCK). For each of the terms, if not already an integer, round to the next highest integer. tCK refers to the application clock period. WR refers to the WR parameter stored in the MRS.

For DQS signals timings are guaranteed with a differential Slew Rate of 2.0 V/ns in differential strobe mode and a Slew Rate of 1 V/ns in single ended mode. 4) The CK / CK input reference level (for timing reference to CK / CK) is the point at which CK and CK cross. The DQS / DQS, RDQS / RDQS, input reference level is the crosspoint when in differential strobe mode. The input reference level for signals other than CK/CK, DQS/DQS, RDQS / RDQS is defined. 5) Inputs are not recognized as valid until VREF stabilizes. During the period before VREF stabilizes, CKE = 0.2 x VDDQ is recognized as low. 6) The output timing reference voltage level is VTT. 7) For each of the terms, if not already an integer, round to the next highest integer. tCK refers to the application clock period. WR refers to the WR parameter stored in the MR. 8) The clock frequency is allowed to change during self-refresh mode or precharge power-down mode. 9) For timing definition, refer to the Component data sheet. 10) Consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers as well as output Slew Rate mis-match between DQS / DQS and associated DQ in any given cycle. 11) MIN (tCL, tCH) refers to the smaller of the actual clock low time and the actual clock high time as provided to the device (i.e. this value can be greater than the minimum specification limits for tCL and tCH). 12) The tHZ, tRPST and tLZ, tRPRE parameters are referenced to a specific voltage level, which specify when the device output is no longer driving (tHZ, tRPST), or begins driving (tLZ, tRPRE). tHZ and tLZ transitions occur in the same access time windows as valid data transitions.These parameters are verified by design and characterization, but not subject to production test. 13) The Auto-Refresh command interval has be reduced to 3.9 µs when operating the DDR2 DRAM in a temperature range between 85 °C and 95 °C. 14) 0 °C≤ TCASE ≤ 85 °C 15) 85 °C < TCASE ≤ 95 °C 16) A maximum of eight Auto-Refresh commands can be posted to any given DDR2 SDRAM device. 17) The tRRD timing parameter depends on the page size of the DRAM organization. See Table 5 “Ordering Information for Lead-Free Products (RoHS Compliant)” on Page 5. 18) The maximum limit for the tWPST parameter is not a device limit. The device operates with a greater value for this parameter, but system performance (bus turnaround) degrades accordingly. 19) Minimum tWTR is two clocks when operating the DDR2-SDRAM at frequencies ≤ 200 ΜΗz. 20) User can choose two different active power-down modes for additional power saving via MRS address bit A12. In “standard active powerdown mode” (MR, A12 = “0”) a fast power-down exit timing tXARD can be used. In “low active power-down mode” (MR, A12 =”1”) a slow power-down exit timing tXARDS has to be satisfied. 21) WR must be programmed to fulfill the minimum requirement for the tWR timing parameter, where WRMIN[cycles] = tWR(ns)/tCK(ns) rounded up to the next integer value. tDAL = WR + (tRP/tCK). For each of the terms, if not already an integer, round to the next highest integer. tCK refers to the application clock period. WR refers to the WR parameter stored in the MRS.

ODT turn off time max is when the bus is in high impedance. Both are measured from tAOFD. Both are measured from tAOFD, which is interpreted differently per speed bin.

Unit “tCK.AVG” represents the actual tCK.AVG of the input clock under operation. Unit “nCK” represents one clock cycle of the input clock, counting the actual clock edges. Note that in DDR2-400 and DDR2-533, “tCK” is used for both concepts. Example: tXP = 2 [nCK] means; if Power Down exit is registered at Tm, an Active command may be registered at Tm + 2, even if (Tm + 2 - Tm) is 2 x tCK.AVG + tERR.2PER(Min). 2) ODT turn on time min is when the device leaves high impedance and ODT resistance begins to turn on. ODT turn on time max is when the ODT resistance is fully on. Both are measured from tAOND, which is interpreted differently per speed bin. For DDR2-667/800, tAOND is 2 clock cycles after the clock edge that registered a first ODT HIGH counting the actual input clock edges. 3) ODT turn off time min is when the device starts to turn off ODT resistance. ODT turn off time max is when the bus is in high impedance. Both are measured from tAOFD, which is interpreted differently per speed bin. For DDR2-667/800, if tCK(avg) = 3 ns is assumed, tAOFD is 1.5 ns (= 0.5 x 3 ns) after the second trailing clock edge counting from the clock edge that registered a first ODT LOW and by counting the actual input clock edges.
