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.
Flash
Flash memory provides non-volatility and reprogrammability, making it a strong competitor to ROM. Flash is often preferred over ROM because it can be updated.

TrustZone
TrustZone is a security extension that can use ROM to store secure boot code and cryptographic keys, making it a complementary technology.
Secure Boot
Secure Boot often relies on ROM to store the initial bootloader and cryptographic keys for verifying subsequent boot stages, making it a complementary technology.
UEFI
UEFI (Unified Extensible Firmware Interface) is a modern BIOS replacement that can be stored in ROM or Flash memory. The ROM stores the initial UEFI code.
