11. Auto Refresh & Self Refresh
* Note : 1. Active power down : one or more bank active state.
2. Precharge power down : both bank precharge state.
3. The auto refresh is the same as CBR refresh of conventional DRAM.
No precharge commands are required after Auto Refresh command.
During t
RC
from auto refresh command, any other command can not be accepted.
4. Before executing auto/self refresh command, both banks must be idle state.
5. (S)MRS, Bank Active, Auto/Self Refresh, Power Down Mode Entry.
6. During self refresh mode, refresh interval and refresh operation are performed internally.
After self refresh entry, self refresh mode is kept while CKE is LOW.
During self refresh mode, all inputs expect CKE will be don’t cared, and outputs will be in Hi-Z state.
During t
RC
from self refresh exit command, any other command can not be accepted.
Before/After self refresh mode, burst auto refresh cycle (2K cycles ) is recommended.
