Self refresh entry command (/CS, /RAS, /CAS, CKE = Low, /WE = High)
After the command execution, self refresh operation continues while CKE remains low. When CKE goes high, the
Synchronous DRAM exits the self refresh mode. During self refresh mode, refresh interval and refresh operation are
performed internally, so there is no need for external control. Before executing self refresh, all banks must be
precharged.
