Introduction to DDR SDRAM
DDR (Doub le Da ta Rate) SDRAM is similar to conve ntion al SDRAM,
but doub les the rate by transferring data twice per cyc le. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM mod-
ules rather than 168-pin DIMM modules used by SDR SDRAM. Two types of
DDR a re av ailable a t the time of writin g : PC1600 & PC2100. PC1600 DDR
SDRAM running at 100MHz will produ ce about 1.6GB/s memory ban dwidth.
PC2100 runnin g at 133MHz will prod uce 2.1GB/ s memory bandwid th. Hig h
memory band width makes DDR an id eal s olution for hig h performance PC,
workstations and servers.

CPU Core Speed Derivation Procedure
If

100MHz
Core/Bu s ratio
=
14
then
CPU core s peed
=
Host Clock x Core /Bus ratio
=
100MHz x 14
=
