Extended Data Out Dynamic Random Access Memory definition
<storage> (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".
