In this post, we will understand the difference between PROM and EPROM −
It is not reusable.
It is not expensive.
Once a PROM has been processed, it can’t be reversed.
This means, its memory is permanent.
Storage endurance of PROM is high.
It is completely sheathed during a plastic cowl.
It is a write-only ROM.
If there is an error or bug while writing on PROM, it can’t be changed- making it unusable.
It is known as the older version of EPROM.
It is better than EPROM in terms of flexibility and scalability.
A bipolar transistor is used in PROM.
It is a reusable ROM.
It is expensive in comparison to PROM.
The processes of EPROM can be reversed.
The storage endurance of EPROM is higher in comparison to PROM.
It is boxed during a rock crystal window so that ultraviolet radiation rays can transfer through it.
It is a type of ROM that is read and write.
If there is an error or bug while writing to EPROM, it can be reversed, and used again.
It can be considered as the modern version of PROM.
It is less flexible and scalable in comparison to PROM.
An MOS transistor is used in EPROM.
