EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It’s a type of non-volatile memory that can store small amounts of data even when power is removed. EEPROMs are commonly used in applications where persistent storage of configuration settings or small amounts of user data is required, such as in microcontrollers, embedded systems, and electronic devices like USB flash drives and SD cards. Unlike traditional ROM (Read-Only Memory), EEPROM can be electrically erased and reprogrammed multiple times, making it flexible and suitable for applications that require frequent updates to stored data.

Feature

One prominent feature of EEPROM is its ability to be electrically erased and reprogrammed, allowing for multiple read-write cycles. This feature makes EEPROM ideal for storing data that may need frequent updates or modifications, such as configuration settings or user preferences in electronic devices. Additionally, EEPROMs typically offer low-power consumption, fast access times, and compatibility with a wide range of microcontrollers and electronic systems. Moreover, they often have a relatively high endurance, allowing them to withstand many read and write cycles before wearing out.
