Notes:
1. All DDR2 SDRAM commands are defined by states of
CS , RAS , CAS , WE and CKE at the rising edge of the clock.
2. Bank addresses BA[1:0] determine which bank is to be operated upon. For (E)MRS BA selects an (Extended) Mode Register.
3. Burst reads or writes at BL = 4 can not be terminated or interrupted. See Burst Interrupt in section 8.5 for details.
4. VREF must be maintained during Self Refresh operation.
5. Self Refresh Exit is asynchronous.
6. The Power Down does not perform any refresh operations. The duration of Power Down Mode is therefore limited by the
refresh requirements outlined in section 8.9.
