Notes:
*1.
All entries assume the CKE was High during the proceeding clock cycle and the current clock cycle.
Illegal to bank in specified state; entry may be legal in the bank specified by BA, depending on the state
of that bank.
Illegal if any bank is not idle.
Must satisfy bus contention, bus turn around, and/or write recovery requirements.
NOP to bank precharging or in idle state.
May precharge bank spesified by BA (and AP).
SELF command should only be issued after the last read data have been appeared on DQ.
MRS command should only be issued on condition that all DQ are in Hi-Z.
t
RRD
must be satisfied for other banks.
