Extended Data Out Random Access Memory

    (EDO DRAM, EDO RAM) A type of DRAM designed to
   access nearby memory locations faster than FPM DRAM.

   Extended Data Out DRAM (EDO-DRAM) allows the data outputs to
   be kept active after the CAS\ signal goes inactive, using an
   additional signal OE\ to control the data outputs.  This can
   be used in pipelined systems for overlapping accesses where
   the next cycle is started before the data from the last cycle
   is removed from the bus.

   EDO DRAM is primarily used with Intel's Pentium processors
   since with slower processors there is no significant
   performance gain.  To make use of the advanced features of EDO
   an appropriate chipset, such as Triton, must be used.  In
   early 1995, EDO DRAM was available for computers from
   Micron, Gateway 2000, and Intel Corporation; since then
   other manufactures followed suit.

   Note that in comparison to Burst EDO EDO is sometimes
   referred to as "Standard EDO".
