1. DESELECT and NOP are functionally interchangeable.
2. BA0–BA1 provide device bank address and A0–A11 (128MB) or A0–A12 (256MB, 512MB) provide device row address.
3. BA0–BA1 provide device bank address; A0–A9 (128MB, 256MB) or A0–A9 , A11( 512MB) provide device column
4. Applies only to read bursts with auto precharge disabled; this command is undefined (and should not be used) for
5. A10 LOW: BA0–BA1 determine which device bank is precharged. A10 HIGH: all device banks are precharged and
6. This command is AUTO REFRESH if CKE is HIGH, SELF REFRESH if CKE is LOW.
7. Internal refresh counter controls device row addressing; all inputs and I/Os are “Don’t Care” except for CKE.
8. BA0–BA1 select either the mode register or the extended mode register (BA0 = 0, BA1 = 0 select the mode register;
