Introduction to EEPROM: What It Is and Why It Matters
EEPROM, which stands for Electrically Erasable Programmable Read-Only Memory, is a type of non-volatile memory used in computers and electronic devices to store small amounts of data that must be saved when power is removed. Unlike traditional EPROM, EEPROM can be erased and reprogrammed electrically, byte by byte, without requiring ultraviolet light. This flexibility makes EEPROM indispensable in modern electronics, from microcontrollers and automotive systems to IoT devices and medical equipment. The global EEPROM market was valued at approximately USD 1.2 billion in 2025 and is projected to grow at a CAGR of 5.8% through 2030, driven by rising demand for smart devices and industrial automation.
