[DM CONTROL]
[Power DOWN]
DM is defined as the data mask for writes. During writes,DM masks input data word by word. DM
to write mask latency is 0.
The purpose of CLK suspend is power down. CKE is synchronous input except during the self-
refresh mode. A command at cycle is ignored. From CKE=H to normal function, DLL recovery time
is NOT required in the condition of the stable CLK operation during the power down mode.
