Traditional Dynamic Random Access Memories (DRAMs) no longer have adequate bandwidth and access time to keep up with the speed of current microprocessors. In order to increase speed and efficiency many work station and mainframe manufacturers are starting to use high performance memories. This book features coverage of advances in high performance RAM technology. It has been updated to incorporate extra material including the new DDR DRAMs, CiDDR DRAMs, SL=DRAM, the Direct Rambus, SSTL interfaces, and the 16M SGRAM.
