*Note :
1. Active power down : one or more banks active state.
2. Precharge power down : all 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
RFC
from auto refresh command, any other command can not be accepted.
4. Before executing auto/self refresh command, all banks must be idle state.
5. MRS, Bank Active, Auto/Self Refresh, Power Down Mode Entry.
6. During self refresh mode, refresh interval and refresh operation are perfomed 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.
For the time interval of t
RFC
from self refresh exit command, any other command can not be accepted.
Before/After self refresh mode, burst auto refresh cycle (4096 cycles) is recommended.
