Rambus DRAM
RDRAM

   <storage> (RDRAM) A high bandwidth {DRAM}, designed by
   {Rambus, Inc.} of Mountain View, CA.

   RDRAM is used mainly for {video accelerators}, and also in the
   {Ultra 64} from {Nintendo}.  It offers sustained {transfer
   rates} of around 1000 Mbps, compared to 200 Mbps for ordinary
   DRAM.  Although it cannot be used as a direct replacement for
   existing memory, it is likely that it will replace DRAM and
   {SDRAM} as the main memory system in {personal computers} as
   the {bus} speeds required by these machines increase.  SDRAM
   can operate up to around 100MHz, but RDRAM has been
   demonstrated by the manufacturers running at 600MHz.

   The memory is also only 8 or 9 {bits} wide, so the bandwidth
   would increase enormously if it were used in parallel to give
   32 or 64-bit memory.
