Extended Data Out DRAM 1 Direct Rambus DRAM

The last significant improvement in asynchronous DRAM was Burst Extended Data Out DRAM, or BEDO DRAM. In fact, BEDO DRAM is a much faster than EDO DRAM. In some cases, BEDO DRAM competes in performance with SDRAM. However, because SDRAM has the marketplace, BEDO DRAM was short lived and is rarely seen in modern PC's.
