Topic: Read-only memory


  
 Read-only memory - Wikipedia, the free encyclopedia
Hence the BIOS or a bootloader for a computer is often stored in ROM.
Read-only memory (ROM) is a class of storage media used in computers and other electronic devices.
Diode matrix ROM, which was used in small amounts in many computers in the 1960s as well as keyboard encoders for terminals.

 Read-Only Memory
ROM information is etched onto tiny microchips inside the computer, and it can be read by the computer, but not changed.
ROM chips are found almost everywhere in a computer system, from the basic input/output system (BIOS) to peripheral devices like printers and scanners.
A further refinement in ROM technology is EEPROM (Electronically Erasable Programmable Read-Only Memory).

 ROM (READ ONLY MEMORY)
ROM chips are also used to store programs for hand-held computers.
For example, ROM BIOS chips are used to store information for starting up your computer.
Once data is programmed into the ROM chip, its contents cannot be altered.

 Programmable read-only memory - Wikipedia, the free encyclopedia
A programmable read-only memory (PROM) or field programmable read-only memory (FPROM) is a form of digital memory where the setting of each bit is locked by a fuse or antifuse.
As these read-only memories were both erasable, programmable and re-programmable, they constitute the first production implementation of the concept of EPROM and EEPROM memories, in manufacture prior to 1963.
Read-only means that, unlike the case with conventional memory, the programming cannot be changed (at least not by the end user).

 Read-Only Memory from FOLDOC
ROM is also used for storage of the lowest level bootstrap software (firmware) in a computer.
ROM is inherently non-volatile storage - it retains its contents even when the power is switched off, in contrast to RAM.
In its most general sense, the term might be used for any storage system whose contents cannot be altered, such as a gramophone record or a printed book; however, the term is most often applied to semiconductor integrated circuit memories, of which there are several types, and CD-ROM.

 read-only memory - a Whatis.com definition - see also: ROM
ROM is "built-in" computer memory containing data that normally can only be read, not written to.
Unlike a computer's random access memory (RAM), the data in ROM is not lost when the computer power is turned off.
ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on.

 [No title]
Early microcomputers lacked ROM memory and had to be started by entering a bootstrap program, or sometimes the whole program that the user would want to run, directly into the computers memory via switchs on the front panel.
ROM (Read Only Memory) would play an important role in making computers easier to use.
The EPROM (Erasable Programable Read Only Memory) would allow designers to program ROMs themselves and even erase them by exposing them to ultravoilet light (this is why EPROMs have a clear window on top).

 Read only memory (ROM):
To use the ROM to implement a logic function, the address lines are used as the variable inputs, and the contents of the memory are the function values.
Usually the memory has a word length of more than 1 bit; typically 4 or 8 bits, so several functions can be implemented simultaneously.
Often, today, devices requiring 8 or more input variables are implemented using a ROM.

 Read-Only Memory (ROM)
ROM: A regular ROM is constructed from hard-wired logic, encoded in the silicon itself, much the way that a processor is. It is designed to perform a specific function and cannot be changed.
Continuing the "CD" analogy, this technology is analogous to a reusable CD-RW.
Read-only memory is most commonly used to store system-level programs that we want to have available to the PC at all times.

 What is ROM? - A Word Definition From the Webopedia Computer Dictionary
A variation of a ROM is a PROM (programmable read-only memory).
Most personal computers contain a small amount of ROM that stores critical programs such as the program that boots the computer.
Pronounced rahm, acronym for read-only memory, computer memory on which data has been prerecorded.

 Read Only Memory (ROM)
The way a ROM chip works necessitates the programming of complete data when the chip is created.
Flash memory works much faster than traditional EEPROMs because instead of erasing one byte at a time, it erases a block or the entire chip, and then rewrites it.
For this reason, developers created a type of ROM known as programmable read-only memory (PROM).

 READ ONLY MEMORY
ROM chips are loaded with data and programs during manufacture and, unlike RAM (random-access memory) chips, can subsequently only be read, not written to, by computer.
