... B. While applying power, attempt to maintain CKE below 0.2 x VDDQ and ODT undefined, voltage levels at I/Os and outputs must be less than VDDQ during voltage ramp time to avoid DRAM latch- up. During the ramping of the supply voltages, VDD ≥ VDDL ≥ VDDQ must be maintained and is applicable to both AC and DC levels until the ramping of the supply voltages is complete, which is when VDDQ crosses VDDQ min ...

... The mode register is written by asserting LOW on CS#, RAS#, CAS#, WE#, BA0 and BA1, while controlling the state of address pins A0 – A13. The DDR2 SDRAM should be in all bank precharge with CKE already HIGH prior to writing into the mode register. The mode register set command cycle time (tMRD) is required to complete the write operation to the mode register. The mode register contents can be changed using the same command and clock cycle requirements during normal operation as long as all banks are in the precharge state ...

The mode register set command cycle time (tMRD) must be satisfied to complete the write operation to the extended mode register ...

... Therefore, the extended mode register must be programmed during initialization for proper operation. The extended mode register 2 is written by asserting LOW on CS, RAS, CAS, WE, BA0, and HIGH on BA1, while controlling pins A0-A13. The DDR2 SDRAM should be in all bank precharge state with CKE already HIGH prior to writing into extended mode register 2.

... Note: All bits in EMR[3] except BA0 and BA1 are reserved for future use and must be set to 0 when programming the EMR[3]. Truth Tables Operation or timing 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. ...

... The Power Down does not perform any refresh operations. The duration of Power Down Mode is therefore limited by the refresh requirements outlined in this datasheet. 14. CKE must be maintained HIGH while the DDRII SDRAM is in OCD calibration mode. 15. “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 set to “ ...

... Operations already in progress are not affected. DESELECT is also referred to as COMMAND INHIBIT. NO OPERATION (NOP) The NO OPERATION (NOP) command is used to instruct the selected DDR2 SDRAM to perform a NOP (CS# is LOW; RAS#, CAS#, and WE# are HIGH). This prevents unwanted commands from being registered during idle or wait states. Operations already in progress are not affected ...

... REFRESH command. SELF REFRESH The SELF REFRESH command can be used to retain data in the DDR2 SDRAM, even if the rest of the system is powered down. When in the self refresh mode, the DDR2 SDRAM retains data without external clocking. All power supply inputs (including VREF) must be maintained at valid levels upon entry/exit and during SELF REFRESH operation ...
