Definitions for "Read-only memory"
Memory that cannot be modified. The system can use (read) the data contained in ROM but cannot change it.
Non-volatile memory that is written once, usually during card production.  It is used to store operating systems and algorithms employed by the microprocessor in an integrated circuit card during transactions.
A memory device (usually electronic memory circuits) that may only be read by a computer. The data stored in ROM memory is permanent (non-volatile) and is not lost when electricity is turned off to the computer.
