(2) (Read Only Memory) A memory chip that permanently stores instructions and data. Also known as "mask ROM," its content is created in the last masking stage of the chip manufacturing process, and it cannot be changed. Stand-alone ROM chips and ROM banks in microcontroller chips are used to hold control routines for myriad applications. ROMs were also widely used to hold the BIOS in early PCs as well as plug-in cartridges for video games.

Although EPROMs, EEPROMs, and particularly flash memory, are the kinds of non-volatile storage one hears about more often, ROM is a mature, inexpensive technology that is easy to integrate into the design of any CMOS chip.

ROMs Are Secure
Unlike flash memory, which can be updated, the data in ROM chips cannot be tampered with. If encryption keys and other security codes are stored in a ROM, they cannot be altered unless the chip is physically replaced (see secure boot). See memory types, RAM, EEPROM and flash memory.


ROMs Are Everywhere
Cartridges that contain nothing more than a ROM chip are used to hold games and educational programs. The yellow ROM cartridge in this image (bottom right) contains a program for the LeapPad Learning System for preschoolers.

In Rom 15:15-20 he describes his goal with the words "in order that I might be a minister ([TEXT NOT REPRODUCIBLE IN ASCII]) of Christ Jesus to the [gentile] nations, serving the gospel of God as a priest in order that the offering of the gentiles [that is, a genitive of apposition; the gentiles are the offering Paul makes (24)] might be acceptable [to God], set apart as holy by the Holy Spirit."
