EEprom
EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It is a non-volatile memory that retains stored data without power and can be both programmed and erased using electrical signals. Unlike static RAM or conventional PROM, EEPROM allows data to be updated in place, typically at the byte level, though some devices support small page-sized operations.
Most EEPROM devices use floating-gate transistor technology. The stored data corresponds to the presence or absence
Types include serial EEPROMs (I2C or SPI interfaces) and traditional parallel EEPROMs. Serial devices are common
Applications include saving device configuration, calibration data, and small firmware parameters that must survive power loss.
