Write Operations (WP =High )
Byte Write: (Write operation during WP =High status )
A write operation requires an 8-bit device address word with R/W = “0”. Then the EEPROM sends acknowledgment
"0" at the ninth clock cycle. After these, the 128kbit EEPROM receives 2 sequence 8-bit memory address words.
Upon receipt of this memory address, the EEPROM outputs acknowledgment "0". After receipt of 8-bit write data, the
EEPROM outputs acknowledgment "1" (NO ACK) . Then the EEPROM write operations are not allowed.

Page Write:
The page write is the same sequence as the byte write. The page write is initiated by a start condition, device address
word and memory address(n) with every ninth bit acknowledgment"0". But after inputting write data(Dn) , the
EEPROM outputs acknowledgment "1" (NO ACK ). Then the EEPROM write operations are not allowed.
