512M gDDR2 SDRAM
K4N51163QC-ZC
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, ODT and CKE. Also the DLL is disabled upon entering precharge power-
down or slow exit active power-down, but the DLL is kept enabled during fast exit active power-down. In power-down
mode, CKE low and a stable clock signal must be maintained at the inputs of the gDDR2 SDRAM, and ODT should be in
a valid state but all other input signals are “Don’t Care”. CKE low must be maintained until tCKE has been satisfied.
Power-down duration is limited by 9 times tREFI of the device.
The power-down state is synchronously exited when CKE is registered high (along with a Nop or Deselect command).
CKE high must be maintained until tCKE has been satisfied. A valid, executable command can be applied with power-
down exit latency, tXP, tXARD, or tXARDS, after CKE goes high. Power-down exit latency is defined at AC spec table of
this data sheet.
