Abstract: | New advanced architectures in DRAM interfaces seek to close the ever-widening performance gap between DRAM and microprocessor and to break the bandwidth bottleneck in graphics systems. We present an overview of five of these interfaces: EDO, SDRAM, RDRAM, CDRAM, and 3D-RAM. EDO will soon replace conventional DRAM, and SDRAM will partly take over in 66-MHz and higher frequency systems. Other interfaces will initially find target markets that exploit their unique features, and then seek wider market acceptance. Eventually, advances in DRAM will contribute to the trend toward a system on a chip |
