Electronics - Semiconductor Memory - Discussion

EEPROM stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be saved when power is removed, e.g., calibration tables or device configuration.

EPROM or erasable programmable read only memory, is a type of memory chip that retains its data when its power supply is switched off. In other words, it is non-volatile.

(NVRAM) Non-volatile random-access memory is random-access memory that retains its information when power is turned off, which is described technically as being non-volatile. This is in contrast to the most common forms of random access memory today, dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both require continual power in order to maintain their data.

The best-known form of NVRAM memory today is flash memory.

@Lays.

Non-volatile means non-erasable (i.e) that is data can be retrieved later when your computer gets restarted. Your data should not be lost in both.

The main difference is EPROM will erase whole data and reprogrammed but in EEPROM a particular data which you don't need can be erased and to be reprogrammed.

I have a doubt i.e., both are non-volatile, than what is the difference between those 2.
