[SELF REFRESH]
Self -refresh mode is entered by issuing a REFS command (/CS=/RAS=/CAS=L,/WE=H,CKE=L).
Once the self-refresh is initiated, it is maintained as long as CKE is kept low. During the self-
refresh mode, CKE is asynchronous and the only enable input, all other inputs including CLK are
disabled and ignored, so that power consumption due to synchronous inputs is saved. To exit the
self-refresh, supplying stable CLK inputs, asserting DESEL or NOP command and then asserting
CKE for longer than tXSNR/tXSRD.
