Electrically Erasable Programmable Read-Only Memory (EEPROM)
Overview
The EEPROM API provides read and write access to Electrically Erasable Programmable Read-Only Memory (EEPROM) devices.
EEPROMs have an erase block size of 1 byte, a long lifetime, and allow overwriting data on byte-by-byte access.
