Mask ROM consists of a grid of [https://www.~~theepochtimes~~.com~~/n3/search~~/?q=~~phrase~~%~~20strains phrase strains] (the tackle input) and bit traces (the info output),~~ selectively joined with transistor switches, and ~~may signify~~ an arbitrary look-up ~~desk~~ with an everyday ~~physical format~~ and predictable propagation delay.

Knowledge stored in ROM cannot be electronically modified after the manufacture of the memory gadget. Learn-solely memory is helpful for storing software program that is never changed through the life of the system, often known as firmware. Software program applications, comparable to video games, for programmable gadgets may be distributed as plug-in cartridges containing ROM. Strictly speaking, learn-only memory refers to onerous-wired memory, corresponding to diode matrix or a mask ROM integrated circuit (IC), that can't be electronically modified after manufacture. Although discrete circuits may be altered in precept, by the addition of bodge wires and the removal or replacement of parts, ICs can't. Correction of errors, or updates to the software, require new devices to be manufactured and to change the put in system.

The term "ROM" is typically used to discuss with a ROM device containing particular software program or a file with software to be saved in a writable ROM gadget. For instance, Memory Wave users modifying or replacing the Android working system describe files containing a modified or replacement working system as "custom ROMs" after the kind of storage the file used to be written to, and they might distinguish between ROM (where software and data is stored, often Flash memory) and RAM.
