3.5.5
Power-down is entered when CKE is registered LOW (no accesses can be in progress). If power-down occurs
when all banks are idle, this mode is referred to as precharge power-down; if power-down occurs when there is a
row active in any bank, this mode is referred to as active power-down. Entering power-down deactivates the input
and output buffers, excluding CK, CK and CKE. The DLL is still running in Power Down mode, so for maximum
power savings, the user has the option of disabling the DLL prior to entering Power-down. In that case, the DLL
must be enabled after exiting power-down, and 200 clock cycles must occur before a Read command can be
issued. In power-down mode, CKE Low and a stable clock signal must be maintained at the inputs of the DDR
SDRAM, and all other input signals are “Don’t Care”. However, power-down duration is limited by the refresh
requirements of the device, so in most applications, the self refresh mode is preferred over the DLL-disabled
power-down mode.
The power-down state is synchronously exited when CKE is registered HIGH (along with a Nop or Deselect
command). A valid, executable command may be applied one clock cycle later.
