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 to high, the M12L128324A 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.
Burst stop command
( CS , WE = Low, RAS , CAS = High)
This command terminates the current burst operation.
Burst stop is valid at every burst length.
