(electronics) A type of read-only memory which can be written to once (write-once read-many memory/WORM), and thereafter becomes fixed in value.

Alternative spelling of programmable read-only memory

(computing) A form of random access memory that requires fewer transistors per bit than SRAM, but in which each bit needs to be refreshed regularly to retain its contents.

A type of semiconductor memory that uses bistable latching circuitry (flip-flop) to store each bit.

A type of random access memory which stores bits as changes in resistance/conductance.

Synonym of hyperthymesia

(electronics) a type of computer memory that can be written to repeatedly, but does not lose its value when the system is powered off, because it is battery backed
