Double data rate SYNCHRONOUS DRAMs in high performance applications

Double Data Rate Synchronous DRAMs are recently introduced SDRAM type products that can offer an evolutionary change with performance advantages for all Memory Systems. These advantages are based on a synchronous I/O interface and dual edge clock based data bus with improved internal architecture that enables faster data throughput rates. Architectural differences are discussed between various memory solutions and future trends in Synchronous DRAMs. The device functionality and timing are explained as compared with single data rate SDRAMs. Performance estimations are shown for present and future DDR SDRAM products when compared with traditional commodity type DRAMs or single edge clock SDRAMs
