Difference between PROM and EPROM:

  1. PROM is a programmable memory while EPROM is electronically programmable memory.
  2. We can write instructions on PROM only once while on EPROM we can write instructions many times.
  3. The instructions cannot be erased from PROM while can be erased by EPROM with the help of electrical pulses.
