Difference Between EPROM and EEPROM

EPROM and EEPROM: Find the Difference Between EPROM and EEPROM

Both of these are types of ROM or Random Access Memory, but there is a difference between EPROM and EEPROM. But before we get into that, let us know a bit more about ROM. It is a type of non-volatile memory that we can’t modify at all or can modify only a bit. But we can feasibly erase and then reprogram the modern ROM in some ways.

Various modified versions of RAM are present- two of these are EPROM and EEPROM. One can easily erase and reprogram both of these, but the speed of performing these is very less. The process of erasing requires some special equipment. Thus, we can only do it a limited number of times.

There is a basic difference between EPROM and EEPROM. One can erase the data from EPROM using the UV (Ultra Violet) rays. On the other hand, erasing data from EEPROM requires the usage of electric signals. Read ahead to discover more differences between them in a tabular form.

What is EPROM?

The term EPROM is an acronym for Erasable Programmable ROM. It is a type of ROOM that we write and read optically. For writing an associated EPROM, the storage cells it contains must stay in the initial stages. EPROM consists of reduced storage permanency in comparison with PROM. The EPROM, as a result, becomes receptive to electrical noise and unwanted radiation. The construction of EPROM requires the usage of MOS transistors.

What is EEPROM?

The term EPROM is an acronym for Electrically Erasable Programmable ROM. This type of ROM makes use of electricity for erasing the content in EEPROM. The memory in EEPROM might be non-volatile. It is capable of storing a very little amount of data and information used in computer BIOS/ laptop. It acts as a replacement for EPROM as well as PROM.
