EEPROM

EEPROM is an abbreviation for Electrically Erasable Programmable Read-Only Memory which is another form of semiconductor device that unusually includes capability to write but is actually rewritable with the stored data being retained even in the absence of power supply. Whereas it is derived from EEPROM known as flash memory, it is not suitable for bulk storage but for small essential data. EEPROM is installed on circuit boards and it is used where small data sets such as configuration settings and instructions are required to be stored, and since it is non-volatile, data can be retrieved when the device has shut down.

‍EEPROM is used for the following:

The primary advantage of EEPROM is its ability to retain data without power, making it ideal for several key applications:

• ‍Configuration of Parameters: These are the kind of information that can be saved using the EEPROM because if the device is switched off for a while then switched on again, it should not be reconfigured.
• ‍Secure Storage: It also gives archiving of confidential info for example, keys for encrypting data, user IDs and certificates from unauthorized citizens.
• ‍Event Logging Management: EEPROM is non-volatile making it possible to record events such as time scheduled in the system analysis and diagnostic as well as the past system performance.
