† For execution of these commands, A0 – A11(n) and DQM(n) are don’t care entries.
‡ All other unlisted commands are considered as vendor-reserved or illegal commands.
§ On cycle n, the device executes the respective command (listed in Table 1). On cycle (n+1), the device enters power-down mode.
¶ A bank is no longer in an access operation one cycle after the last data-out cycle of a read operation, and two cycles after the last data-in cycle
of a write operation. Neither the PDE nor the HOLD command is allowed on the cycle immediately following the last data-in cycle of a write
operation.
# If setup time from CKE high to the next CLK high satisfies tCESP, the device executes the respective command (listed in Table 1). Otherwise,
either the DESL or the NOOP command must be applied before any other command.
Legend:
n
= CLK cycle number
L
= Logic low
H
= Logic high
X
= Don’t care, either logic low or logic high
T
= Bank T
B
= Bank B
deac = Deactivated
