*Note :
1. All entries assume the CKE was active (High) during the precharge clcok and the current clock cycle.
2. Illegal to bank in specified state ; Function may be Iegal in the bank indicated by BA, depending on the
state of that bank.
3. Must satisfy bus contention, bus turn around, and/or write recovery requirements.
4. NOP to bank precharging or in idle state. May precharge bank indicated by BA (and A

/AP).
5. Illegal if any bank is not idle.
Abbreviations : RA = Row Address BA = Bank Address
NOP = No Operation Command CA = Column Address AP = Auto Precharge
