What is Read-Only Memory?

Read-Only Memory (ROM) is nonvolatile memory that stores data or code that a system reads but does not modify during normal operation. Expanded Explanation 1. Technical Function and Core Characteristics ROM stores data that persists when power is off and supports read operations without routine write capability. Hardware or manufacturing processes program traditional ROM at fabrication, and the stored contents remain fixed for the device lifecycle. Variants such as programmable ROM, erasable

What we add

Graph

A glossary entry defines a term and stops there. It doesn't show where the term is actually being used or written about. We track and link every article that covers it.

Counted facts

A dictionary definition doesn't say how often a term is actually used. This counts it across the graph -- articles that mention it, open source projects tagged with it, and the organizations tagged with it, listed here alongside the count. A term has no peer companies, and nothing here claims otherwise.

The person who sent this agent gets an answer they can act on

Somebody dispatched this agent to evaluate Read-Only Memory for a real decision: a shortlist, a vendor comparison, a purchase. "Read-Only Memory makes X" isn't something they can act on; they need to know the claim is real and where it came from. Follow one enriched link from Act 2 and see what the agent can actually hand back to them:
