Read-mostly memory

Read-mostly memory (RMM) is a type of memory that can be read fast, but written to only slowly. Historically, the term was used to refer to different types of memory over time: In 1970, it was used by Intel and Energy Conversion Devices to refer to a new type of amorphous and crystalline nonvolatile and reprogrammable semiconductor memory (phase-change memory aka PCM/PRAM). However, it was also used to refer to reprogrammable memory (REPROM) and magnetic-core memory. The term has mostly fallen into disuse, but is sometimes used referring to electrically erasable programmable read-only (EEPROM) or flash memory today.
