All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of /CK. Output (read) data is referenced to the crossings of CK and /CK (both directions of crossing). CKE Input Clock Enable: CKE HIGH activates, and CKE LOW deactivates internal clock signals, and device input buffers and output drivers. Taking CKE LOW provides PRECHARGE POWER DOWN and SELF REFRESH operation (all banks idle), or ACTIVE POWER DOWN (row ACTIVE in any bank). CKE is synchronous for POWER DOWN entry and exit, and for SELF REFRESH entry. CKE is asynchronous for SELF REFRESH exit, and for output disable. CKE must be maintained high throughout READ and WRITE accesses. Input buffers, excluding CK, /CK and CKE are disabled during POWER DOWN. Input buffers, excluding CKE are disabled during SELF REFRESH. CKE is an SSTL_2 input, but will detect an LVCMOS LOW level after Vdd is applied. /CS Input Chip Select : Enables or disables all inputs except CK, /CK, CKE, DQS and DM. All commands are masked when CS is registered high. CS provides for external bank selection on systems with multiple banks. CS is considered part of the command code. BA0, BA1 Input Bank Address Inputs: BA0 and BA1 define to which bank an ACTIVE, Read, Write or PRECHARGE command is being applied. A0 ~ A9 Input Address Inputs: Provide the row address for ACTIVE commands, and the column address and AUTO PRECHARGE bit for READ/WRITE commands, to select one location out of the memory array in the respective bank. A8 is sampled during a precharge command to determine whether the PRECHARGE applies to one bank (A8 LOW) or all banks (A8 HIGH). If only one bank is to be precharged, the bank is selected by BA0, BA1. The address inputs also provide the op code during a MODE REGISTER SET command. BA0 and BA1 define which mode register is loaded during the MODE REGISTER SET command (MRS or EMRS). /RAS, /CAS, /WE Input Command Inputs: /RAS, /CAS and /WE (along with /CS) define the command being entered. DM0 ~ DM3 Input Input Data Mask: DM(0~3) is an input mask signal for write data. Input data is masked when DM is sampled HIGH along with that input data during a WRITE access. DM is sampled on both edges of DQS. Although DM pins are input only, the DM loading matches the DQ and DQS loading. DM0 corresponds to the data on DQ0-Q7; DM1 corresponds to the data on DQ8-Q15; DM2 corresponds to the data on DQ16-Q23; DM3 corresponds to the data on DQ24-Q31. DQS I/O Data Strobe: Output with read data, input with write data. Edge aligned with read data, centered in write data. Used to capture write data. DQ0 ~ DQ31 I/O Data input / output pin : Data Bus VDD/VSS Supply Power supply for internal circuits and input buffers. VDDQ/VSSQ Supply Power supply for output buffers for noise immunity. VREF Supply Reference voltage for inputs for SSTL interface.

Before entering Mode Register Set mode, all banks must be in a precharge state and MRS command can be issued after tRP period from Prechagre command. 3. If a Read with Autoprecharge command is detected by memory component in CK(n), then there will be no command presented to activated bank until CK(n+BL/2+tRP). 4. If a Write with Autoprecharge command is detected by memory component in CK(n), then there will be no command presented to activated bank until CK(n+BL/2+1+tDPL+tRP). Last Data-In to Prechage delay(tDPL) which is also called Write Recovery Time (tWR) is needed to guarantee that the last data has been completely written. 5. If A8/AP is High when Precharge command being issued, BA0/BA1 are ignored and all banks are selected to be precharged.

Operational procedures other than those specified may result in undefined operation. Power must first be applied to VDD, then to VDDQ, and finally to VREF (and to the system VTT). VTT must be applied after VDDQ to avoid device latch-up, which may cause permanent damage to the device. VREF can be applied anytime after VDDQ, but is expected to be nominally coincident with VTT. Except for CKE, inputs are not recognized as valid until after VREF is applied. CKE is an SSTL_2 input, but will detect an LVCMOS LOW level after VDD is applied. Maintaining an LVCMOS LOW level on CKE during power-up is required to guarantee that the DQ and DQS outputs will be in the High-Z state, where they will remain until driven in normal operation (by a read access). After all power supply and reference voltages are stable, and the clock is stable, the DDR SDRAM requires a 200us delay prior to applying an executable command. Once the 200us delay has been satisfied, a DESELECT or NOP command should be applied, and CKE should be brought HIGH. Following the NOP command, a PRECHARGE ALL command should be applied. Next a EXTENDED MODE REGISTER SET command should be issued for the Extended Mode Register, to enable the DLL, then a MODE REGISTER SET command should be issued for the Mode Register, to reset the DLL, and to program the operating parameters. After the DLL reset, tXSRD(DLL locking time) should be satisfied for read command. After the Mode Register set command, a PRECHARGE ALL command should be applied, placing the device in the all banks idle state. Once in the idle state, two AUTO REFRESH cycles must be performed. Additionally, a MODE REGISTER SET command for the Mode Register with the reset DLL bit deactivated low (i.e. to program operating parameters without resetting the DLL) must be performed. Following these cycles, the DDR SDRAM is ready for normal operation. 1. Apply power - VDD, VDDQ, VTT, VREF in the following power up sequencing and attempt to maintain CKE at LVCMOS low state. (All the other input pins may be undefined.) • VDD and VDDQ are driven from a single power converter output. • VTT is limited to 1.44V (reflecting VDDQ(max)/2 + 50mV VREF variation + 40mV VTT variation. • VREF tracks VDDQ/2. • A minimum resistance of 42 Ohms (22 ohm series resistor + 22 ohm parallel resistor - 5% tolerance) limits the input current from the VTT supply into any pin. • If the above criteria cannot be met by the system design, then the following sequencing and voltage relationship must be adhered to during power up. Votage description Sequencing Voltage relationship to avoid latch-up VDDQ After or with VDD < VDD + 0.3V VTT After or with VDDQ < VDDQ + 0.3V VREF After or with VDDQ < VDDQ + 0.3V 2. Start clock and maintain stable clock for a minimum of 200usec. 3. After stable power and clock, apply NOP condition and take CKE high. 4. Issue Extended Mode Register Set (EMRS) to enable DLL. 5. Issue Mode Register Set (MRS) to reset DLL and set device to idle state with bit A8=High. (An additional 200 cycles(tXSRD) of clock are required for locking DLL) 6.

The mode register is program via MRS command. This command is issued by the low signals of /RAS, /CAS, /CS, /WE and BA0. This command can be issued only when all banks are in idle state and CKE must be high at least one cycle before the Mode Register Set Command can be issued. Two cycles are required to write the data in mode register. During the the MRS cycle, any command cannot be issued. Once mode register field is determined, the information will be held until resetted by another MRS command.

The burst length determines the maximum number of column locations that can be accessed for a given Read or Write command. Burst lengths of 2, 4 or 8 locations are available for both the sequential and the interleaved burst types. Reserved states should not be used, as unknown operation or incompatibility with future versions may result. When a Read or Write command is issued, a block of columns equal to the burst length is effectively selected. All accesses for that burst take place within this block, meaning that the burst wraps within the block if a boundary is reached. The block is uniquely selected by A1-Ai when the burst length is set to two, by A2-Ai when the burst length is set to four and by A3-Ai when the burst length is set to eight (where Ai is the most significant column address bit for a given configuration). The remaining (least significant) address bit(s) is (are) used to select the starting location within the block. The programmed burst length applies to both Read and Write bursts. Accesses within a given burst may be programmed to be either sequential or interleaved; this is referred to as the burst type and is selected via bit A3. The ordering of accesses within a burst is determined by the burst length, the burst type and the starting column address, as shown in Burst Definitionon Table CAS LATENCY The Read latency or CAS latency is the delay in clock cycles between the registration of a Read command and the Rev. 0.3 / Jun. 2005 18 11HY5DU323222QP availability of the first burst of output data. The latency can be programmed 3 or 4 clocks. If a Read command is registered at clock edge n and the latency is m clocks, the data is available nominally coincident with clock edge n + m. Reserved states should not be used as unknown operation or incompatibility with future versions may result. DLL RESET The DLL must be enabled for normal operation. DLL enable is required during power up initialization, and upon returning to normal operation after having disabled the DLL for the purpose of debug or evaluation. The DLL is automatically disabled when entering self refresh operation and is automatically re-enabled upon exit of self refresh operation. Any time the DLL is enabled, 200 clock cycles must occur to allow time for the internal clock to lock to the externally applied clock before an any command can be issued. OUTPUT DRIVER IMPEDANCE CONTROL The HY5DU323222 supports both Half strength driver and Matched impedance driver, intended for lighter load and/or point-to-point environments. Half strength driver is to define about 50% of Full drive strength which is specified to be SSTL_2, Class II, and Matched impedance driver, about 30% of Full drive strength. Rev. 0.3 / Jun. 2005 19 11HY5DU323222QP EXTENDED MODE REGISTER SET (EMRS) The Extended Mode Register controls functions beyond those controlled by the Mode Register; these additional functions include DLL enable/disable, output driver strength selection(optional). These functions are controlled via the bits shown below. The Extended Mode Register is programmed via the Mode Register Set command ( BA0=1 and BA1=0) and will retain the stored information until it is programmed again or the device loses power. The Extended Mode Register must be loaded when all banks are idle and no bursts are in progress, and the controller must wait the specified time before initiating any subsequent operation. Violating either of these requirements will result in unspecified operation.

Data latched at both rising and falling edges of Data Strobes(DQS) : DQ, DM(0~3). 4. Minimum of 200 cycles of stable input clocks after Self Refresh Exit command, where CKE is held high, is required to complete Self Refresh Exit and lock the internal DLL circuit of DDR SDRAM. 5. 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). 6. tHP = minimum half clock period for any given cycle and is defined by clock high or clock low (tCH, tCL). tQHS consists of tDQSQmax, the pulse width distortion of on-chip clock circuits, data pin to pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers. 7. DQS, DM and DQ input slew rate is specified to prevent double clocking of data and preserve setup and hold times. Signal transitions through the DC region must be monotonic.
