... HIGH. Write Write operations are initiated when both CE and WE are LOW and OE is HIGH. The X28HT512 supports both a CE and WE controlled write cycle. That is, the address is latched by the falling edge of either CE or WE, whichever occurs last. Similarly, the data is latched internally by the rising edge of either CE or WE, which- ever occurs first ...
