Power-down is synchronously entered when CKE is registered LOW coincident with a
NOP or DES command. CKE is not allowed to go LOW while either an MRS, MPR,
ZQCAL, READ, or WRITE operation is in progress. CKE is allowed to go LOW while any of
the other legal operations (such as ROW ACTIVATION, PRECHARGE, auto precharge, or
REFRESH) are in progress. However, the power-down I
cable until such operations have been completed. Depending on the previous DRAM
state and the command issued prior to CKE going LOW, certain timing constraints must
be satisfied (as noted in Table 73). Timing diagrams detailing the different power-down
mode entry and exits are shown in Figure 98 on page 152 through Figure 107 on
page 157.
1. If slow-exit mode precharge power-down is enabled and entered, ODT becomes asynchro-
Entering power-down disables the input and output buffers, excluding CK, CK#, ODT,
CKE, and RESET#. NOP or DES commands are required until
at which time all specified input/output buffers will be disabled. The DLL should be in a
locked state when power-down is entered for the fastest power-down exit timing. If the
DLL is not locked during power-down entry, the DLL must be reset after exiting power-
down mode for proper READ operation as well as synchronous ODT operation.
During power-down entry, if any bank remains open after all in-progress commands are
complete, the DRAM will be in active power-down mode. If all banks are closed after all
in-progress commands are complete, the DRAM will be in precharge power-down mode.
Precharge power-down mode must be programmed to exit with either a slow exit mode
or a fast exit mode. When entering precharge power-down mode, the DLL is turned off in
slow exit mode or kept on in fast exit mode.
The DLL remains on when entering active power-down as well. ODT has special timing
constraints when slow exit mode precharge power-down is enabled and entered. Refer
to “Asynchronous ODT Mode” on page 172 for detailed ODT usage requirements in slow
exit mode precharge power-down. A summary of the two power-down modes is listed in
Table 74 on page 152.
