Note:
15.The internal Write time of the memory is defined by the overlap of WE,CE

or CE

V
, BHE and/or BLE = V
. All signals must be ACTIVE to initiate
a write and any of these signals can terminate a write by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal
that terminates the write.
