... READ: The AT28HC256 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 con- tention in their system ...
