The WE256K32-XG2TXE stores data at the memory location
determined by the address pins. When CS and OE are low and
WE is high, this data is present on the outputs. When CS and
OE are high, the outputs are in a high impedance state. This
two line control prevents bus contention.
NOTES:
OE may be delayed up to tACS - tOE after the
falling edge of CS without impact on tOE or by
tACC - tOE after an address change without
impact on tACC.
