Burst Extended Data Out DRAM
BEDO
Burst EDO

    (Burst EDO, BEDO) A variant on EDO DRAM in which
   read or write cycles are batched in bursts of four.  The
   bursts wrap around on a four byte boundary which means that
   only the two least significant bits of the CAS address are
   modified internally to produce each address of the burst
   sequence.  Consequently, burst EDO bus speeds will range from
   40MHz to 66MHz, well above the 33MHz bus speeds that can be
   accomplished using Fast Page Mode or EDO DRAM.

   Burst EDO was introduced sometime before May 1995.
