Doul information rate random approach storage chips are a grade of chips that supply doul the working speed of one information rate storage chips. DDR333 is a sub kind of DDR chips.

Computers traditionally procedure information at a adjust rhythm--its "clock speed." one information rate chips just prompted storage approximately at that rataplan. DDR chips, by demarcation, are also alive on the offbeat, which supplies doul the storage speed.

The 333 postfix on DDR333 mentions to its information delivery rate, in millions of diliver per moment. So, a DDR333 chip can execute 333 "megatransfers" per moment.

fresher DDR techs DDR2 and DDR3 have replaced DDR. when the quickest dilivery rate for DDR is 400 megatransfers per moment, DDR2 chips can achieve 1,066 as DDR3 chips can act up to 1,600. You may not mingle chips from the three geneses to supply storage on the similar machine.
