read-only memory
Write-protected data storage
Read-only memory is computer memory whose contents can be read but not modified during normal operation.
The data is typically written once during manufacturing or setup and retained even when power is off.
Abbreviated ROM, it contrasts with RAM (random-access memory), which loses its contents when powered down.
The game cartridge contained read-only memory.
