Page Write The page write mode of the CAT28C256 (essentially an extended BYTE WRITE mode) allows from bytes of data to be programmed within a single EEPROM write cycle. This effectively reduces the byte−write time by a ...

DATA Polling DATA polling is provided to indicate the completion of write cycle. Once a byte write or page write cycle is initiated, attempting to read the last byte written will output the complement of that data on I/O indeterminate) ...
