Figure 14. Auto Refresh and Self Refresh
Notes
:
1. Active power down: one or more banks active state.
2. Precharge power down: both banks 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 excuting 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 except CKE will be “Don’t Care”, and outputs will be in Hi-Z state.
During t
RC
from self refresh exit command, any other comman can not be accepted.
Before/after self refresh mode, burst auto refresh (2K cycles) is recommended.
