Advantages of EPROM | disadvantages of EPROM memory

This page covers advantages and disadvantages of EPROM memory. It mentions EPROM advantages or benefits and EPROM disadvantages or drawbacks. It provides links on various topics on EPROM basics.

What is EPROM

Introduction:
EPROM is the short form of Erasable Programmable ROM. It is programmed similar to PROM. EPROMs can be erased as well as re-programmed repeatedly.

It is easy to erase EPROM completely by exposing it to ultraviolet light. This is due to availability of window in the top of the device to allow light to reach the silicon. This brings entire chip to its initial un-programmed state. This is called reset of the EPROM device. Ability to re-program EPROMs make it essential part in software development and testing inspite of higher cost compare to PROMs.

Benefits or advantages of EPROM

Following are the benefits or advantages of EPROM:
➨It retains memory even without power. Hence no external memory is required.
➨It is re-programmable as mentioned above.
➨It is very cost effective.

Drawbacks or disadvantages of EPROM

Following are the disadvantages of EPROM:
➨Transistors used in EPROM have higher resistance.
➨It has high static power consumption.
➨It requires UV light exposure to erase the program and can not be erased using electrical signal.
➨It is not possible to erase particular byte like EEPROM and entire contents are erased.
➨EPROM need to removed from its board or test jig in order to erase or re-program the device.
➨UV based EPROM requires sometime to erase as opposed to EEPROM which is instant.
