Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware.

Apr 10, 2024 · ROM is an acronym for Read-Only Memory. It refers to a type of computer memory that stores data permanently. A ROM memory chip contains hard-wired instructions that you can't change. It's also nonvolatile, which means it retains its contents even if the device loses power.

An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile.

Mar 18, 2025 · Memory plays a crucial role in how devices operate, and one of the most important types is Read-Only Memory (ROM). Unlike RAM (Random Access Memory), which loses its data when the power is turned off, ROM is designed to store essential information permanently.

Apr 7, 2025 · This article classifies the Read-Only Memories, their hierarchies as well as the ways of programming the chips with focus on their importance in the stability and operations of systems. What is ROM?

Oct 30, 2023 · Read-Only Memory (ROM), is a type of electronic storage that comes built in to a device during manufacturing. You’ll find ROM chips in computers and many other types of electronic products; VCRs, game consoles, and car radios all use ROM to complete their functions smoothly.

The ROM process is the simplest of all memory processes, usually requiring only one layer of polysilicon and one layer of metal. There are no special film deposition or etch requirements, so yields are the highest among all the equivalent-density memory chips.

ROM stands for Read-only Memory. It is a type of memory that does not lose its contents when the power is turned off. For this reason, ROM is also called non-volatile memory. Because ROMs are deployed in such a wide variety of applications, there are different types of ROMs suited to different applications across the industry.

Sep 6, 2022 · PROM, or Programmable Read Only Memory, invented in 1956, addressed the first two issues and partly discussed the third. It did this by allowing a generic design to be …

Read-only memory (ROM) is a type of computer memory that permanently stores data used to operate the system. ROM holds essential data and instructions necessary for the proper functioning of a computer system. It is a non-volatile memory meaning information stored in a ROM memory chip remains unchanged when the electronic device is turned off.
