What Does Extended Data Out Random Access Memory (EDO RAM) Mean?
Extended data out random access memory (EDO RAM/DRAM) is an early type of dynamic random access memory (DRAM) chip which was designed to improve the performance of fast page mode DRAM (FPM DRAM) that was used in the 1990s. Its main feature was that it eliminated wait times by allowing a new cycle to start while retaining the data output buffer from the previous cycle active, which allows a degree of pipelining (overlap in operation) that improved performance.
Techopedia Explains Extended Data Out Random Access Memory (EDO RAM)
Extended data out dynamic random access memory was introduced in 1994 and began to replace fast page mode DRAM by 1995 when Intel first introduced the 430FX chipset that supports EDO DRAM. Before that, EDO DRAM could replace FPM DRAM, but if the memory controller was not specifically designed for the EDO, then the performance remained the same as FPM.
