Random Read:
This is a read operation with defined read address. A random read requires a dummy write to set read
address. The EEPROM receives a start condition, device address word (R/W=0) and memory address 2
×
8-bit sequentially. The EEPROM outputs acknowledgment “0” after receiving memory address then enters
a current address read with receiving a start condition. The EEPROM outputs the read data of the address
which was defined in the dummy write operation. After receiving acknowledgment “1”(no
acknowledgment) and a following stop condition, the EEPROM stops the random read operation and
returns to a standby state.

Notes: 1. Don't care bits for 128k and 256k.
2. Don't care bit for 128k.
3. 2nd device address code (#) should be same as 1st (@).
