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.
FLOATIN GATE EEPROM SPEED (ACCESS TIME) is about 150 nsec. Write time 10 msec Byte/Page. Endurance 10E4-10E5 cycles.  Cost moderate. EEPROM limitations are the write speed and the endurance.
