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.
since with slower processors there is no significant
performance gain. To make use of the advanced features of EDO
early 1995, EDO DRAM was available for computers from
other manufactures followed suit.
Note that in comparison to
Burst EDO EDO is sometimes
referred to as "Standard EDO".
