WebFeb 26, 2024 · What are the four types of ROM? The types of ROM are MROM (Masked Read Only Memory), PROM (Programmable Read Only Memory), EPROM (Erasable Programmable Read Only Memory) / … WebROM generally is still used to refer to all of these types generically. The motherboard has some type of ROM chip that holds the firmware, which in PC parlance is usually called the BIOS, or Basic Input Output System, though it is being replaced these days with EFI firmware.

Programmable read-only memory (PROM), or one-time programmable ROM (OTP), can be written to or programmed via a special device called a PROM programmer. Typically, this device uses high voltages to permanently destroy or create internal links (fuses or antifuses) within the chip. Consequently, a PROM … See more Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices.
