An EEPROM has a limited life for erasing and reprogramming, now reaching a million operations in modern EEPROMs.
Originally, EEPROMs were limited to single-byte operations, which made them slower, but modern EEPROMs allow multi-byte page operations.
EEPROMs can be programmed and erased in-circuit, by applying special programming signals. A cross section of legacy UV-EPROM structure.ĮEPROM (also called E 2PROM) stands for electrically erasable programmable read-only memory and is a type of non-volatile memory used in computers, integrated in microcontrollers for smart cards and remote keyless systems, and other electronic devices to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed.ĮEPROMs are organized as arrays of floating-gate transistors.
