TRUTH TABLE – COMMANDS AND DQM OPERATION
NOTES:
1. CKE is HIGH for all commands except SELF REFRESH.
2. A0-A10 define the op-code written to the mode register.
3. A0-A10 provide row address, and BA0, BA1 determine which bank is made active.
4. A0-A7 (x32) provide column address; A10 HIGH enables the auto precharge feature (nonpersistent), while A10 LOW disables
5. A10 LOW: BA0, BA1 determine the bank being precharged. A10 HIGH: All banks precharged and BA0, BA1 are “Don’t Care.”
6. AUTO REFRESH if CKE is HIGH, SELF REFRESH if CKE is LOW.
7. Internal refresh counter controls row addressing; all inputs and DQs are “Don’t Care” except for CKE.
8. Activates or deactivates the DQs during WRITEs (zero-clock delay) and READs (two-clock delay).
