What is ROM?

ROM (Read-Only Memory) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be easily altered or reprogrammed. It is commonly used to store firmware, which provides the initial instructions for a device when it is powered on, such as the BIOS in a computer or the operating system in embedded systems.

What other technologies are related to ROM?

ROM Competitor Technologies

SRAM

SRAM is a type of volatile memory that can be used as a substitute for ROM in some applications where reprogrammability is desired during operation (but requires power). ROM is non-volatile.

OTP

OTP (One-Time Programmable) memory provides non-volatility similar to ROM, but allows programming once. It can be used in similar applications as ROM but offers some flexibility.

RAM

RAM is a competitor. Like SRAM, it's volatile but offers reprogrammability and can sometimes replace ROM when data changes. It usually can not be used as a substitute for ROM because of its volatile nature.
