Electrically Erasable Programmable Read-Only Memory, or EEPROM, is a type of non-volatile memory chip used in electronic devices like computers to store small amounts of data. It allows the erasing and reprogramming of a single data byte, unlike other forms of memory that can erase only certain parts of it. EEPROM has replaced PROM and EPROM in most applications.
This technology was invented by Eli Harari at Hughes Aircraft in 1977 and later improved by George Perlegos at Intel in 1978.
EEPROM is a modified version of EPROM that uses electrical impulses to erase and program data instead of ultraviolet (UV) signals. It is also a type of primary memory, which means that information stored on it can be quickly accessed by the processor.
FAQs
What does EEPROM stand for?
EEPROM stands for Electrically Erasable Programmable Read-Only Memory.
What is the difference between EPROM and EEPROM?
EPROM (Erasable Programmable Read-Only Memory) uses ultraviolet (UV) signals to erase data and requires a special tool to reprogram it. EEPROM, on the other hand, uses electrical impulses to erase and program data, making it easier to use and more flexible for modern electronic devices.
What is EEPROM used for?
EEPROM is used to store small amounts of data in electronic devices, including computers, microcontrollers, and other embedded systems.
Final thoughts
EEPROM is an essential type of non-volatile primary memory used in most electronic devices today. By allowing the erasing and reprogramming of a single data byte, it provides greater flexibility and convenience than older forms of read-only memory.
