DDR5 Memory Enables Next-Generation Computing

Computing main memory transitions may only happen once a decade, but when they do, it is a very exciting time in the industry. When JEDEC announced the publication of the JESD79-5 DDR5 SDRAM standard in 2021, it signaled the beginning of the transition to DDR5 server and client dual-inline memory modules (Server RDIMMs, Client UDIMMs and SODIMMs). We are now firmly on this path of enabling the ... » read more

Scaling DDR5 RDIMMs To 5600 MT/s

Looking forward to 2022, the first of the DDR5-based servers will hit the market with RDIMMs running at 4800 megatransfers per second (MT/s). This is a 50% increase in data rate over top-end 3200 MT/s DDR4 RDIMMs in current high-performance servers. DDR5 memory incorporates a number of innovations, such as Decision Feedback Equalization (DFE), and a new DIMM architecture which enable that speed... » read more

Five Key Changes Coming With DDR5 DIMMs

On July 14th of last year, JEDEC announced the publication of the DDR5 SDRAM standard. This signaled the nearing industry transition to DDR5 server dual-inline memory modules (DIMM). DDR5 memory brings a number of key enhancements that will bring great performance and power benefits in next generation servers. Scaling Data Rates to 6.4 Gb/s You can never have enough memory bandwidth, and DD... » read more

Memory Buffer Chips: Satisfying Amdahl’s Law To Sustain Moore’s Law

Moore’s Law, the observation that the available transistors in an integrated circuit doubles every two years, has driven the semiconductor and IT industries to unparalleled growth over the last 50+ years. These transistors have been used in CPUs to increase the number of parallel execution units and instruction fetches, expand the levels of on-chip cache (and overall capacity), support spe... » read more
