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 log as CKE is
kept low.During the self-refresh mode, CKE is asynchronous and the only enabled
input (but asynchronous), all other inputs including CK0 are disabled and ignored, and
power consumption due to synchronous inputs is saved. To exit the self-refresh,
supplying stable CK0 inputs, asserting DESEL or NOP command and then asserting
CKE(REFSX). After tRC from REFSX both banks are in the idle state and a new
command can be issued after tRC, but DESEL or NOP commands must be asserted
till then.
