Extended Data Out Dynamic Random Access Memory
<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
