EEPROM
EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile memory used in computing and electronics to store small amounts of data that must be retained when power is removed. It allows individual bytes to be erased and reprogrammed electrically, making it more flexible than older ROM types like EPROM. EEPROM is commonly used in embedded systems for storing configuration settings, calibration data, or device parameters.
Developers should learn about EEPROM when working with embedded systems, microcontrollers, or IoT devices where persistent storage of small data sets is required without the complexity of a full file system. It is essential for scenarios like storing user preferences, device IDs, or firmware updates in hardware projects using platforms like Arduino or Raspberry Pi. Understanding EEPROM helps optimize memory usage and ensure data integrity in low-power or resource-constrained environments.
