The memory device is compatible with the I2C memory standard. This is a two wire serial
interface that uses a bi-directional data bus and serial clock. The memory carries a built-in 4-bit
unique device type identifier code (1010) in accordance with the I2C bus definition.
Serial Clock (SCL)
The SCL input is used to strobe all data in and out of the memory.
Serial Data (SDA)
The SDA pin is bi-directional, and is used to transfer data in or out of the memory.
