Reduced DRAM cycle times with extended data-out

Abstract

As system speeds increase, DRAM manufacturers are developing methods to decrease the cycle times of DRAMs. The most common version of DRAM is FAST PAGE MODE (FPM) but the addition of a feature known as extended data-out (EDO) may become more common because it allows shorter page cycle times with only a minor functional change from FP. Because the device with EDO doesn't turn off the output drivers when CAS goes HIGH, it can have a shorter cycle time than FP.
