Apr 10, 2024 · ROM is an acronym for Read-Only Memory. It refers to computer memory chips containing hard-wired instructions that can not be changed. It is nonvolatile, meaning it retains its contents even when power is removed. An example of ROM is the cartridge used with video game consoles.

ROM stands for Read-Only Memory. It is a non-volatile memory that is used to store important information which is used to operate the system. As its name refers to read-only memory, we can only read the programs and data stored on it. It is also a primary memoryunit of the computersystem. It contains some electronic fuses that can be programmed for...
As shown in below diagram, there are k input lines and n output lines in it. The input address from which we wish to retrieve the ROM content is taken using the k input lines. Since each of the k input lines can have a value of 0 or 1, there are a total of 2 k addresses that can be referred to by these input lines, and each of these addresses conta...
The internal structure of ROM have two basic components. 1. Decoder 2. OR gates A circuit known as a decoderconverts an encoded form, such as binary coded decimal, or BCD, into a decimal form. As a result, the output is the binary equivalent of the input. The outputs of the decoder will be the output of every OR gate in the ROM. Let’s use a 64 x 4 ...
A small, long-lasting battery within the computer powers the ROM, which is made up of two primary components: the OR logic gates and the decoder. In ROM, the decoder receives binary input and produces decimal output. The decoder’s decimal output serves as the input for ROM’s OR gates. ROM chips have a grid of columns and rows that may be switched o...
ROM is a non-volatile memory.Information stored in ROM is permanent.Information and programs stored on it, we can only read and cannot modified.Information and programs are stored on ROM in binary format.Now we will discuss the types of ROMone by one: 1. MROM (Masked read-only memory):We know that ROM is as old as semiconductor technology. MROM was the very first ROM that consists of a grid of word lines and bit lines joined together transistor switches. This type of ROM data is physically encoded in the circuit and only be programmed during fabric...
It is cheaper than RAMand it is non-volatile memory.It is more reliable as compared to RAM.Its circuit is simple as compared to RAM.It doesn’t need refreshing time because it is static.It is a read-only memory, so it cannot be modified.It is slower as compared to RAM.Software applications, such as video games, for programmable devices can be distributed as plug-in cartridges containing ROM. Strictly speaking, read-only memory refers to hard-wired memory, such as diode matrix or a mask ROM integrated circuit (IC), that cannot be electronically changed after manufacture.
May 6, 2023 · It is used in video games, optical storage, compact discs (CD) such as a CD-ROM, as well as devices such as calculators or laser printers, and many others. Many people confuse ROM and RAM and often talk about them interchangeably, but they have several key differences.
