Burst Extended Data Out DRAM
     
         (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.
