  static RAM
  
     <storage> (SRAM) Random access memory in which each bit of
     storage is a bistable flip-flop, commonly consisting of
     cross-coupled inverters.  It is called "static" because it
     will retain a value as long as power is supplied, unlike
     dynamic random access memory (DRAM) which must be regularly
     refreshed.  It is however, still volatile, i.e. it will lose
     its contents when the power is switched off, in contrast to
     ROM.  SRAM is usually faster than DRAM but since each bit
     requires several transistors (about six) you can get less bits
     of SRAM in the same area.  It usually costs more per bit than
     DRAM and so is used for the most speed-critical parts of a
     computer (e.g. cache memory) or other circuit.
