What is EEPROM and major advantages?

[mucahitdemir]

EPROM, in full erasable programmable read-only memory, form of computer memory that does not lose its content when the power supply is cut off and that can be erased and reused. EPROMs are generally employed for programs designed for repeated use but that can be upgraded with a later version of a program.

Need to protect an even smaller section of critical code? The Lockable ID page feature is a 128-byte memory space separate from the main array. This feature is intended to be used for storing things like factory calibration settings, manufacturing data, MAC addresses, or other identifying information that can be programmed and then set to read-only.

Secondly, EEPROM will not be erased if you remove power from it, but it won't hold onto your data indefinitely. Electrons can drift out of the transistors and through the insulator, effectively erasing the EEPROM over time. That said, this usually occurs over the course of years (although it can be accelerated by heat). Most manufacturers say that your data is safe on EEPROM for 10 years or more at room temperature.

And there's one more thing you should keep in mind when selecting an EEPROM device for your project. EEPROM capacity is measured in bits and not bytes. A 256K EEPROM will hold 256Kbits of data, in other words, just 32KB.

A bit is the most fundamental measurement of memory size.
