EEPROM and EPROM are both types of memory storage elements. They first came about in the 1970s. Each of these elements can be reprogrammed, and they are mainly used in hardware programming.

Though EEPROM and EPROM are both acronyms, they both stand and mean something different.

EEPROM stands for Electronically Erasable Read-Only Memory. It was the most used cell type memory until flash memory came about.

EPROM stands for Erasable Programmable Read-Only memory. Another difference is how they are erased.

EPROM is erased with exposure to UV light. EEPROM is erased electronically. It is easy for users to modify both types of memory.

EPROM stands for Erasable Programmable Read-only memory, while EEPROM stands for Electronically Erasable Read-Only Memory. These are two different forms of the memory storage element.

EPROM has a transparent quartz crystal. In EPROM, UV light is used to erase content. EPROM is an older version of the technology. It was the first reprogrammable ROM made. In order to erase content, the EPROM chip must be removed from the computer circuit in other to erase and reprogram computer BIOS.

However, in EEPROM, contents are erased through the use of electrical signals. It is a much modern version than EPROM. EEPROM does not have to be removed before the chip can be erased and reprogrammed.

EPROM's need to be erased with exposure to UV light and EROM's can be erased electronically. EPROM's have a quartz window in the package to expose the chip to UV light.

EPROM means erasable programmable read-only memory. This is a type of PROM that can be completely removed or erased if it would be exposed to ultraviolet rays. Once the data has been erased, it can be reprogrammed so that new data can be stored. The EEPROM stands for Electrically Erasable Read Only Memory.

The data that will be stored here can only be removed if they are exposed to various electrical signals. These two can be easy to modify by users depending on the type of data that they would like to place on the RAM. Another difference between the two is that the EPROM would need to be removed from the computer so that the data can be removed. The EEPROM will not require this anymore.
