ABBREVIATIONS:
H=High Level, L=Low Level, X=Don't Care
BA=Bank Address, RA=Row Address, CA=Column Address, NOP=No Operation
NOTES:
1. All entries assume that CKE was High during the preceding clock cycle and the current clock cycle.
2. ILLEGAL to bank in specified state; function may be legal in the bank indicated by BA, depending
on the state of that bank.
3. Must satisfy bus contention, bus turn around, write recovery requirements.
4. NOP to bank precharging or in idle state. May precharge bank indicated by BA.
5. ILLEGAL if any bank is not idle.
6. Refer to Read with Auto-Precharge in page 26
7. Refer to Write with Auto-Precharge in page 25
ILLEGAL = Device operation and/or data-integrity are not guaranteed.
