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 (8-bit
for 8kbit to 16kbit EEPROMs, 2
×
8-bit for 32kbit and 64kbit EEPROMs) 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.
