EPROM

Idealogic’s Glossary

EEPROM is an acronym that stands for Erasable Programmable Read-Only Memory, this is a type of memory that can be programmed and once programmed the information is stored even when the power is not passed on to it. Usually the data of EPROMs is written by an external computer and then the chip is plugged to a circuit board.

In order to repulse or wipe out information from an EPROM, the chip is pulled out of the circuit and subjected to extreme ultraviolet light for a maximum of 20 minutes. However, EPROMs are no longer in use and are succeeded by a much efficient variety known as EEPROM.

Why is not EPROM used these days?

As mentioned earlier, EPROM technology is now considered outdated due to several reasons, with the three most significant being:It was earlier pointed that the technology in use for the EPROM is outdated due to the following reasons:

Erasing Constraints: Because to erase data one has to use ultra-violet light EPROMs were not very convenient to use and that is why they have largely been phased out by easier to use technologies.

Slower Speed: In EPROMs; rewriting and erasing the data is time consuming and may take as much as 20 minutes and above solely on the erasing step and for this reason it is not efficient as some of the other technologies.

Technological Advancements: New generation memory technologies have outcompared EPROMs in terms of performance and flexibility and therefore are seldom employed in most uses.
