falling edge of CK. A Delay Locked Loop (DLL) circuit is
driven from the clock inputs and output timing for read
operations is synchronized to the input clock.

clocks, CKE0 initiates the Power Down Mode or the Self
Refresh Mode.
when LOW and disables the command decoder when HIGH.
When the command decoder is disabled, new commands
are ignored but previous operations continue. Rank 0 is
selected by S0; Rank 1 is selected by S1. The input signals
also disable all outputs (except CKE and ODT) of the
register(d) on the DIMM when both inputs are high. When S
is HIGH, all register outputs (except CK, ODT and Chip
select) remain in the previous state.
