Homonym: PROM (Dance)
PROM, or Programmable Read-Only Memory, is a type of non-volatile memory used in computers and electronic devices. Unlike regular RAM, which loses its data when powered off, PROM retains information even when the power is turned off. It is programmed once during manufacturing, making it useful for storing firmware or software that does not need to be changed frequently.
PROM can be contrasted with other types of memory, such as EPROM (Erasable Programmable Read-Only Memory) and EEPROM (Electrically Erasable Programmable Read-Only Memory), which allow for data to be rewritten. PROM is typically used in applications where data integrity and stability are crucial, such as in embedded systems and microcontrollers.
