Commands
SELF REFRESH
The SELF REFRESH command is used to place the device in self refresh mode. The self
refresh mode is used to retain data in the SDRAM while the rest of the system is pow-
ered down. When in self refresh mode, the device retains data without external clocking.
The SELF REFRESH command is initiated like an AUTO REFRESH command, except
that CKE is disabled (LOW). After the SELF REFRESH command is registered, the inputs
become “Don’t Care,” with the exception of CKE, which must remain LOW.
DEEP POWER-DOWN
The DEEP POWER-DOWN (DPD) command is used to enter deep power-down mode,
achieving maximum power reduction by eliminating the power to the memory array. To
enter DPD, all banks must be idle. While CKE is LOW, hold CS# and WE# LOW, and hold
RAS# and CAS# HIGH at the rising edge of the clock. To exit DPD, assert CKE HIGH.
