EEPROM

EEPROM is the abbreviation of Electrically Erasable Programmable Read-Only Memory. EEPROM is a non-volatile memory used in devices that are required to hold small amounts of data. Found in computers, microcontrollers and remote keyless systems EEPROM can be used in almost any large or small decides used in everyday life.

The read-only memory or ROM can be erased and reprogrammed through the application of electrical voltages. EEPROM chips can be modified whilst still in a computer system and their non-volatile functionality means memory can be retrieved even after having the device or computer has been turned off and back on again.

Benefits to EEPROM Memory

There are many benefits to using EEPROM memory in a computer or electronic device. The ability to erase the entire contents of an EEPROM chip as well as being able to erase single bytes per section. As well, a variety of interfaces are available for EEPROM with both serial and parallel buses. Programming capabilities of EEPROM are easy and efficient while being programmable without removing from a device board or testing set up.
