WHAT IS ROM? (READ ONLY MEMORY)

  • (^) It is the type of Primary Memory
  • (^) Memory is basically a device that has the capacity to store

information. Moreover, it is the most important component

of a computer system as it cannot perform even simple

tasks without it

  • (^) Basically, computer memory is of two types namely,
  • (^) 1) Primary Memory
  • (^) 2) Secondary Memory

 (^) Features of Read Only

Memory  (^) The ROM has the features as

follows:

  • (^) It is non-volatile in nature.
  • (^) Less costly than the RAM.
  • (^) As, only read operation is allowed therefore,

no changes can occur.

  • (^) It is easy to test the ROM.
  • Due to its nature, it is more reliable than RAM.
  • Does not require any

refreshing.

 (^) Types of Read Only Memory

 There are 4 types of ROM out of them, 3 are the

most common. These are as follows:

  • MROM (masked read only memory)
  • PROM (programmable read only memory)
  • EPROM(erasable and programmable read only

memory)

  • EEPROM(electrically erasable and programmable

read only memory)

PROM (Programmable Read Only

Memory)

  • (^) It is the programmable ROM that the user can

program but only once.

  • (^) The user writes the data and instructions using a PROM

program.

  • (^) After writing once the user cannot change or erase the

data and instructions.

EPROM (Erasable and

Programmable Read Only Memory)

  • (^) We can reprogram this memory by erasing

the data

  • (^) To erase the data it has to be exposed to

ultraviolet light.

  • (^) During the programming, a charge is trapped in the

insulated gate region.

  • (^) It allows users to write new data on it after

erasing.
