EEPROM ( also written E < sup > 2 </ sup > PROM and pronounced " e-e-prom ," " double-e prom ," " e-squared ," or simply " e-prom ") stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be saved when power is removed, e. g., calibration tables or device configuration.

The Electrically Erasable Programmable Read-Only Memory ( EEPROM ) was developed to provide an electrical erase function and has now mostly displaced ultraviolet-erased parts.

Freescale announced the MC9S12XEP100 in May 2006 to further extend the S12X family to 50MHz bus speed and add a Memory protection unit ( based on segmentation ) and a hardware scheme to provide Emulated EEPROM.

The device also features built-in cheat cartridge functionality through a program called the X-Terminator, as well as the Memory Editor, which allows SRAM and EEPROM saved game data to be archived and edited.

Made of PC with the dimensions in the ISO / IEC 7816 ID-1 format ( standard credit card format ), the initial card had a 32kb EEPROM ( Electronically Erasable Programmable Read-Only Memory ) embedded chip running on M-COS ( MyKad Chip Operating System ).

Data storage can be provided by magnetic tape, battery-backed RAM and, more recently, non-volatile EEPROM or Flash Memory overwritten in a FIFO continuous loop.

A flash memory is a particular type of EEPROM ( Electrically Erasable Programmable Read Only Memory ).
