SAN JOSE, Calif. – Oct. 15, 2024 – Rambus Inc. (NASDAQ: RMBS), a premier chip and silicon IP provider making data faster and safer, today unveiled industry-first, complete memory interface chipsets for Gen5 DDR5 RDIMMs and next-generation DDR5 Multiplexed Rank Dual Inline Memory Modules (MRDIMMs). These innovative new products for RDIMMs and MRDIMMs will seamlessly extend DDR5 performance with unparalleled bandwidth and memory capacity for compute-intensive data center and AI workloads.

The new Rambus chips include:

  • The Gen5 Registering Clock Driver (RCD), enabling RDIMMs operating at 8000 megatransfers per second (MT/s).
  • The Multiplexed Registering Clock Driver (MRCD) and Multiplexed Data Buffer (MDB), enabling upcoming MRDIMMs running at speeds up to 12,800 MT/s by doubling the bandwidth of the DIMM beyond the native DRAM device speed.
  • The second-generation server Power Management IC (PMIC5030) designed for both DDR5 RDIMM 8000 and MRDIMM 12800, providing ultra-high current at low voltage to support higher speeds and more DRAM and logic chips per module.
