... Device Operation READ: The AT28BV16 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 a high im- pedance state whenever high. This dual line control gives designers increased flexibility in preventing bus contention ...
