Electrically Erasable Programmable Read-Only Memory (EEPROM)
Definition - What does Electrically Erasable Programmable Read-Only Memory (EEPROM) mean?
Electrically Erasable Programmable Read-Only Memory (EEPROM) is a stable, non-volatile memory storage system that is used for storing minimal data quantities in computer and electronic systems and devices, such as circuit boards. This data may be stored, even without a permanent power source, as device configuration or calibration tables.
If storing higher volumes of data that is static (like in USB drives), certain types of EEPROM (like flash memory) are more cost-effective than conventional EEPROM devices.

The following are the primary electrical interface categories for EEPROM devices:
- Serial bus: Serial EEPROM generally functions in three different phases - Address Phase, Data Phase and OP-Code Phase. Most familiar types of serial interface are Microwire, SPI, 1-Wire, I²C and UNI/O.
- Parallel bus: A parallel EEPROM device usually includes a data bus of eight bits and a wide enough address bus for total memory handling. The majority of devices include write-protect and chip select pins. Many microcontrollers also include built-in parallel EEPROM.
