EPROM, which is Erasable Programmable Read-Only Memory, is a kind of ROM used for storing data permanently. Intel developed it in 1971. The most prominent inventor of EPROM is known to be Dov Frohman.

Answer: PROM stands for Programmable Read-Only Memory which is a write-only ROM. It is an older version of EPROM, and the reason for its replacement was its permanent memory which could not be rectified. Once data is stored, it becomes irreversible, making it difficult to work with because humans often make mistakes. On the other hand, EPROM, which stands for Erasable Programmable Read-Only Memory, is the evolved version of PROM and comes with the capacity to make changes. Although it is expensive compared to PROM, it replaced the older version because of its capacity to erase data.

EPROM can store data for more than 10 to 20 years and has a non-volatile memory. However, it was cautioned that reprogramming and erasing should be avoided excessively because the chip has a layer of silicon dioxide that can get damaged in the process. EPROM was not the best version but just a modified one, and it had its drawbacks. It is expensive when compared to its old and new versions. It is not electrically reversible and consumes a lot of electricity. It lacks the facility of erasing data byte by byte and needs to be taken out of the computer physically if one wants to erase data.

EPROM works by using ultraviolet rays. First, a window is designed in the EPROM chip, letting the ultraviolet rays pass through it. This process takes 15 to 20 minutes. In most cases, it is said that a room with normal light lacks the capacity of erasing data due to fewer ultraviolet rays present, but if it is exposed to harsh sunlight, data can be erased. Once the data is erased, it can be used for programming again. This process is called burning and requires a PROM programmer.

Any software that won’t be rectified or updated frequently is a part of Read-Only Memory. One of the major reasons behind the invention of EPROM was the limitation of its older version known as PROM. PROM, which is the acronym of Programmable Read-Only Memory, could store data for a long period without power connection, but once this data is stored, it is not possible to update, erase or change the same. Therefore, if a person stores wrong information, the whole PROM would become useless because the change was irreversible.

This evolution was the need for rectification which was not possible with PROM. As technology progressed, even EPROM got a better version known as EEPROM, the acronym for Electronically Erasable Read-Only Memory. The data in EPROM was with the help of ultraviolet rays. Whereas EEPROM can be erased using a pulse of high voltage. It can be seen that after the arrival of EEPROM, the task of rectification had become very easy compared to the phase of PROM when it was not even an option. EEPROM is also an outdated version of ROM because the electronic world has developed a technology called flash memory.

Answer: EPROM is the acronym for Erasable Programmable Read-Only Memory, which uses ultraviolet rays to erase data. Flash memory is the updated version of EEPROM and erases data using a high voltage pulse. EPROM provides a byte level of erasure which is not available with flash memory as it erases in blocks and not bytes.

EPROM stands for Erasable Programmable Read-Only Memory. It is a kind of ROM (Read Only Memory) that is considered the modified version of the initially used PROM. To understand EPROM, one should know ROM. ROM, which stands for Read-Only Memory, is that memory of devices used to store permanent information.

There have been many reasons behind technical advancement globally, but the most prominent is the need to grow and have better technology. Evolution is a never-ending process. This is as true for technology as anything else in this world. As discussed in the article before, EPROM, which is Erasable Programmable Read-Only Memory, is an evolved form of PROM.

FlashEEPROM

Flash Memory- Flash memory is the most updated version of EPROM, which is used to rectify data with the help of ultraviolet rays and could retain data even without a power supply. Flash memory came into existence in 1984 through an engineer Masuoka Fujio, a native of Japan who worked for Toshiba Corporation. Although he was working on finding a replacement for dynamic random access memory, he invented the evolved version of the EPROM. Also, flash memory is called so because it erases data at once in a flash.

After going through this article, one cannot just learn the significance and full form of EPROM but also realize the technological world’s pace of evolution. Electronics is an ever-changing zone, and even the most advanced version of everything becomes outdated sooner or later. Hence, it is important to know the technical jargon and stay updated in the ever-evolving fast-paced electronic world.

Answer: Non-volatile memory is the permanent memory of an electronic device where permanent information is stored. After the invention of EPROM and its modified versions, this memory can be erased and rectified, making it more convenient to use. Also, non-volatile memory can store data without a continuous power supply.

Answer: EPROM, which is an acronym for Erasable Programmable Read-Only Memory, is a type of reading and writing ROM which uses ultraviolet rays to erase data. It consists of a rock crystal window through which the rays pass and erase memory. It is considered the evolved version of PROM. At the same time, EEPROM stands for Electronically Erasable Programmable Read-Only Memory, a step ahead of EPROM. It can erase data using electric signals. It is an external programming technique with a cell size of 3. EEPROM is faster than EPROM because it takes just five milliseconds to erase data, whereas EPROM takes around 15 to 20 minutes for the same.
