What is EPROM? Know the Definition of EPROM

This time we will explain about EPROM. The explanation that we bring includes the meaning, similarities, and also the differences with EEPROM. So, please see our explanation below. After knowing this information you can know and differentiate between EPROM and EEPROM.

Definition of EPROM

EPROM stands for Eraseable Programmable Read-Only Memory which is a memory chip for storing data when the power supply is off.

Computer memory that can retrieve and store data even when the power supply is turned off and on again is called non-volatile. This memory we can write to the program electrically. Programs in the EPROM can be erased when exposed to ultraviolet light and can still be rewritten.

So, the data in the EPROM will not be lost even if the computer is turned off at that time. In other words, EPROM does not require electrical power to maintain the memory so that the information or data in it is safe. Then how to delete the data in the EPROM? There is a tool you can use to delete the data contained in the EPROM. The tool is called UV PROM Eraser.

The device will emit ultraviolet light into your memory. We recommend that you shine it right on the yellow hole. That way, you can still reuse the EPROM chip as before. You can also fill in new data or information into it. Apart from that, there are other tools that you can also use to erase the EPROM. The tool is called EPROM Rewriter.

Differences and Similarities of EPROM and EEPROM

After understanding the meaning of EPROM and how to delete it, our next explanation is about what is the difference between EPROM and EEPROM and what are the similarities between the two.

Even though they have almost the same name, they are actually different. You can delete the data or information contained in the EEPROM per block by adjusting which address you want to delete. Meanwhile, you cannot delete the data or information contained in the EPROM per block.

Even so, you can delete the data in the EPROM using UV light. Meanwhile, the similarity between EPROM and EEPROM is that EEPROM and EPROM include non-volatile memory. So, both can still store information and data even if the computer is off.

Thus the information that we can provide regarding the understanding, similarities, and also the differences between EPROM and EEPROM. In conclusion, both of them can still save data even if the computer is off. Also, EPROM requires UV light to erase it, while EEPROM you can erase by block.
