What Is Read-Only Memory (ROM)? Definition, Uses and Types
WebThe ROM is a part of the motherboard and vital for your computer’s small but crucial instructions. Read-only memory gives you an idea about the possibility of writing data to ROM. But, modern ROMs have evolved a lot from their predecessors and have advanced capabilities. So, is it really possible to change modern ROM content using the CPU? 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 … See more Discrete-component ROM IBM used capacitor read-only storage (CROS) and transformer read-only storage (TROS) to store microcode for the smaller System/360 models, the 360/85, and the initial two See more Factory programmed Mask ROM is a read-only memory whose contents are programmed by the integrated circuit manufacturer (rather than by the user). The desired memory contents are furnished by the customer to the device manufacturer. The … See more The contents of ROM chips can be extracted with special hardware devices and relevant controlling software. This practice is common for, as a main example, reading the contents of older video game console cartridges.

Atypical 8Mbit ROM would have a cell size of about 4.5µm2 for a 0.7µm feature size process, and a chip area of about 76mm2. An announced 64Mbit ROM, manufactured with a 0.6µm feature size, has a 1.23µm2 cell on a 200mm2 die. The ROM process is the simplest of all memory processes, usually requiring only one layer of campbell greenhouse north branch mi
