| Overview
Extended Data Output Dynamic RAM (EDO DRAM) is up to 25% faster than standard DRAM and reduces the need for level-2 cache memory. EDO DRAMs work very similar to FPM DRAMs. EDO DRAMs have the ability to work within a page like FPM DRAMs. The primary advantage with EDO DRAMs over FPM DRAMs is that EDO DRAMs hold the data valid even after the signal that "strobes" the column address goes inactive. This allows faster microprocessors to manage time more efficiently, performing many tasks without having to attend to slower memory. That is, while the EDO DRAM is retrieving an instruction for the microprocessor, the microprocessor can perform other tasks without worrying that the data will become invalid.
