Extended Data Out DRAM
Extended Data Out, or EDO
DRAM, is the most common type of asynchronous
DRAM used in PCs. A simple way to think of how EDO DRAM
is faster than conventional DRAM is that it allows
a memory access to begin before the last
one has completed. EDO memory has about a 3-5%
performance increase over FPM DRAM memory and about
10% increase over standard asynchronous DRAM.

EDO DRAM is about 10% faster than asynchronous DRAM.

EDO memory was quickly
replaced because EDO memory is really not suitable
for system buses above 75MHz. Be mindful
when buying EDO RAM for an older PC.
Many motherboards, old and new, will not support
EDO RAM. Some motherboards are "EDO tolerant"
in that they will treat EDO as FPM memory
and you will lose any performance gains
from the EDO memory module.
