All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of CK. Internal clock signals are derived from CK/CK. 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 all functions except for disabling outputs, which is achieved asynchronously. Input buffers, excluding CK, CK and CKE , are disabled during power-down and self refresh mode which are contrived for low standby power consumption. CS Input Chip Select : CS enables(registered LOW) and disables(registered HIGH) the command decoder. 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. RAS, CAS, WE Input Command Inputs : RAS, CAS and WE (along with CS) define the command being entered. LDM,UDM Input Input Data Mask : DM 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. DM pins include dummy loading internally, to matches the DQ and DQS loading. For the x16, LDM corresponds to the data on DQ0-DQ7 ; UDM correspons to the data on DQ8-DQ15. BA0, BA1 Input Bank Addres Inputs : BA0 and BA1 define to which bank an ACTIVE, READ, WRITE or PRECHARGE command is being applied. A [n : 0] 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. A10 sampled during a PRECHARGE command determines whether the PRECHARGE applies to one bank (A10 LOW) or all banks (A10 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 determines which mode register ( mode register or extended mode register ) is loaded during the MODE REGISTER SET command. DQ I/O Data Input/Output : Data bus LDQS,UDQS I/O Data Strobe : Output with read data, input with write data. Edge-aligned with read data, centered in write data. it is used to fetch write data. For the x16, LDQS corresponds to the data on DQ0-DQ7 ; UDQS corresponds to the data on DQ8-DQ15. NC - No Connect : No internal electrical connection is present. VDDQ Supply DQ Power Supply : 1.7V to 1.95V. VSSQ Supply DQ Ground. VDD Supply Power Supply : 1.7V to 1.95V. VSS Supply Ground.

It includes Cas latency, addressing mode, burst length, test mode and vendor specific options to make DDR SDRAM useful for variety of applications. The default value of the mode register is not defined, therefore the mode register must be written in the power up sequence of DDR SDRAM. The mode register is written by asserting low on CS, RAS, CAS and WE(The DDR SDRAM should be in active mode with CKE already high prior to writing into the mode register). The states of address pins A0 ~ A12 and BA0, BA1 in the same cycle as CS, RAS, CAS and WE going low are written in the mode register. Two clock cycles are required to complete the write operation in the mode register. Even if the power-up sequence is finished and some read or write operation is executed afterward, the mode register contents can be changed with the same command and two clock cycles. This command must be issued only when all banks are in the idle state. If mode register is changed, extended mode register automatically is reset and come into default state. So extended mode register must be set again. The mode register is divided into various fields depending on functionality. The burst length uses A0 ~ A2, addressing mode uses A3, Cas latency(read latency from column address) uses A4 ~ A6, A7 ~ A12 is used for test mode. BA0 and BA1 must be set to low for proper MRS operation.

EMRS cycle is not mandatory and the EMRS command needs to be issued only when either PASR or DS is used. The default state without EMRS command issued is half driver strength, and Full array refreshed. The extended mode register is written by asserting low on CS, RAS, CAS, WE and high on BA1 ,low on BA0(The DDR SDRAM should be in all bank precharge with CKE already high prior to writing into the extended mode register). The state of address pins A0 ~ A12 in the same cycle as CS, RAS, CAS and WE going low is written in the extended mode register. Two clock cycles are required to complete the write operation in the extended mode register. Even if the power-up sequence is finished and some read or write operations is executed afterward, the mode register contents can be changed with the same command and two clock cycles. But this command must be issued only when all banks are in the idle state. A0 - A2 are used for partial array self refresh and A5 - A6 are used for driver strength control. "High" on BA1 and"Low" on BA0 are used for EMRS. All the other address pins except A0,A1,A2,A5,A6, BA1, BA0 must be set to low for proper EMRS operation. Refer to the table for specific codes.

Input Setup/Hold Slew Rate Derating Input Setup/Hold Slew Rate ∆tIS ∆tIH (V/ns) (ps) (ps) 1.0 0 0 0.8 +50 +50 0.6 +100 +100 This derating table is used to increase tIS/tIH in the case where the input slew rate is below 1.0V/ns. 2. Minimum 3CLK of tDAL(= tWR + tRP) is required because it need minimum 2CLK for tWR and minimum 1CLK for tRP. 3. tAC(min) value is measured at the high Vdd(1.95V) and cold temperature(-25°C). tAC(max) value is measured at the low Vdd(1.7V) and hot temperature(85°C). tAC is measured in the device with half driver strength and under the AC output load condition (Fig.7 in next Page). 4. The specific requirement is that DQS be valid(High or Low) on or before this CK edge. The case shown(DQS going from High_Z to logic Low) applies when no writes were previously in progress on the bus. If a previous write was in progress, DQS could be High at this time, depending on tDQSS. 5.

The Delta Rise/Fall Rate is calculated as 1/SlewRate1-1/SlewRate2. For example, if slew rate 1 = 1.0V/ns and slew rate 2 =0.8V/ns, then the Delta Rise/Fall Rate =-0.25ns/V. 7.

Auto refresh functions are same as the CBR refresh of DRAM. The automatical precharge without row precharge command is meant by "Auto". Auto/self refresh can be issued only at all banks precharge state. 4. BA0 ~ BA1 : Bank select addresses. 5. If A10/AP is "High" at row precharge, BA0 and BA1 are ignored and all banks are selected. 6. During burst write with auto precharge, new read/write command can not be issued. Another bank read/write command can be issued after the end of burst. New row active of the associated bank can be issued at tRP after the end of burst. 7. Burst stop command is valid at every burst length. 8. DM sampled at the rising and falling edges of the DQS and Data-in are masked at the both edges (Write DM latency is 0). 9. This combination is not defined for any function, which means "No Operation(NOP)" in DDR SDRAM.
