IS23SC4442 - 256 BYTE EEPROM
IS23SC4442 contains 256 x 8 bits of EEPROM main memory and a 32 x 1 bit protection PROM memory.
The main memory can be randomly accessed byte by byte.
During memory erase, all 8 bits of a byte are set to logical one.
During memory write, individual bit(s) are set to logical zeros depend on the data
