... White Electronic Designs READ The WE128K32-XXX 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 ...

... White Electronic Designs PAGE WRITE OPERATION The WE128K32-XXX has a page write operation that allows one to 128 bytes of data to be written into the device and consecutively loads during the internal programming period. Successive bytes may be loaded in the same manner after the fi rst data byte has been loaded. An internal timer begins a time out operation at each write cycle. If another write cycle is completed within 150µ ...
