By the late 1990s, JEDEC had a solid DRAM roadmap. Beginning in 1996 and concluding in June 2000, JEDEC developed the DDR (Double Data Rate) SDRAM specification (JESD79). In order to offer significant ...

DDR SDRAMs, DRAMs in short, meet these memory requirements by offering a dense, high-performance, and low-power memory solution, either on a dual in-line memory module (DIMM) or as a discrete DRAM ...

Porto Alegre, Brazil Abstract : This paper deals with reusability issues in the development of a double data rate (DDR) SDRAM controller module for FPGA-based systems. The development of integrated ...

Der Begriff DDR-SDRAM steht für Double Data Rate Synchronous Dynamic Random Access Memory ist ein Typ von RAM (Random Access Memory), der derzeit in vier Versionen auf dem Markt ist (Stand 2016).

Over the past 25 years we have seen the transition from SDRAM (Synchronous Dynamic RAM) to DDR (Double Data Rate) SDRAM, and then to DDR2, DDR3 and DDR4 on a cadence of five year cycles.
