The term ROM has many full forms, but out of which most relevant full form is-

ROM Full Form is – Read-only Memory

ROM is an energy-independent memory used to store an array of immutable data. In English terminology, Read-Only Memory is a memory that works only on reading. Information in such memory is pre-laid during its manufacture (“stitched up”) and does not break down when the power is cut off.

A permanent memory device (ROM) is a type of energy-independent memory used in computers and other electronic devices.

The ROM also includes:

• PPS (PROM) – programmable ROM;
• SPPS (EPROM) – erased reprogramming ROM;
• ESPSU (EEPROM) – electrically erased reprogrammed ROM.

Permanent Memory (ROM – a permanent storage device) usually contains information that should not change during the microprocessor of different programs. Permanent memory is also called ROM (Read Only Memory), which indicates that only reading and storage modes are provided. Permanent memory is energy independent, i.e., it can store information when power is turned off. All permanent memory chips are divided into manufacturer-themed, manufacturer-programmable (ROM), one-time user-programmed (Programmable ROM) and multiple programmed by the user (Erasable PROM). The latter, in turn, are divided into erased electrically and with the help of ultraviolet radiation. EPROM elements with electrical erasure of information include, for example, flash memory chips. They differ from regular EPROMs with high speed of access and rapid erasure of recorded information. This type of memory is now widely used to store BIOS and other permanent information.

What Does ROM Stand For?

ROM stands for – Read-only Memory

ROM (permanent storage device) is a chip on the motherboard, which contains programs, data recorded in the manufacture of the computer and used for internal testing of devices after the computer power and the loading of the operating system in RAM. The totality of this firmware is called BIOS (Basic Input-Output System) – a basic I/O system. BIOS has a computer configuration program (SETUP). It allows you to establish some characteristics of computer devices (a type of video controller, hard drives and disk drives for floppy disks, often also RAM modes, password requests when you start downloading).

The data is recorded in the ROM during production. To do this, a stencil with a certain set of bits is made, which is superimposed on the photosensitive material, and then parts of the surface are etched.

Distinguish:

PPSU (programmable ROM) was developed in the late 1970s by a company called Texas Instruments. In other words, it is possible to program in an operating environment. Such ROMs usually contain an array of tiny jumpers. It is possible to burn a certain jumper, select the right line and column, and then apply high voltage to a certain conclusion of the chip.

EPROM (wiped programmable ROM) allows for a special device, programmatic in operation and erase information. To do this, the chip is exposed to strong ultraviolet light with a certain wavelength for 15 minutes.

PPS also erases EEPROM (Electronically reprogrammed ROM), but unlike PPS, they allow reprogramming by application pulses and do not require special additional devices. But work ten times slower with much less capacity and the price is higher.
