Memory Organization

AT24C04B, 4K SERIAL EEPROM:

Internally organized with 32 pages of 16 bytes each, the 4K requires a 9-bit data

word address for random word addressing.

AT24C08B, 8K SERIAL EEPROM:

Internally organized with 64 pages of 16 bytes each, the 8K requires a 10-bit

data word address for random word addressing.
