What is EDO RAM

A minor modification to the structure of the DRAM changes the device into an EDO (extended data output) DRAM device. In EDO memory, any memory access, including a refresh, stores 256 bits selected by RAS' into latches. These latches hold the subsequent 256 bits of information, so in most programs, that are sequentially executed, that data are available without any wait states.
