EEPROM is a non-volatile memory technology, which means that it can retain data even when the power is turned off. This makes it a reliable option for storing critical information in embedded systems.
The operation of EEPROM involves sending specific signals to the memory cells to write, erase, or read data. When writing data to EEPROM, a write-enable signal is sent along with the data to be stored. This signal enables the memory cells to accept the new data and store it in the specified memory locations.
Erasing data from EEPROM involves resetting the memory cells to their original state. This can be done in a controlled manner by sending specific signals to the memory cells that trigger the erasing process. Unlike traditional ROM, which requires UV light to erase data, EEPROM can be easily erased electrically, making it a more convenient option for reprogramming data.
Overall, EEPROM provides a flexible and reliable way to store and manage data in embedded systems. Its ability to write, erase, and rewrite data electrically makes it a versatile option for applications where data needs to be updated frequently or where non-volatile memory is essential for data retention.
