... Read The AT28HC64BF is accessed like a Static RAM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in the high-impedance state when either high. This dual line control gives designers flexibility in preventing bus contention in their systems ...

... AT28HC64BF will be protected against inadvertent writes. It should be noted that even after SDP is enabled, the user may still perform a byte or page write to the AT28HC64BF. This is done by preceding the data to be written by the same 3-byte command sequence used to enable SDP ...
