## Summary
Serial EEPROM is a type of nonvolatile memory that uses arrays of floating-gate transistors to store small amounts of data. Unlike traditional EEPROM, it communicates with external devices via a serial interface, allowing individual bytes to be erased and reprogrammed in-circuit through special signals. It is commonly used in computers and microcontrollers for small-scale data storage.
