Rambus expands its portfolio of DDR5 memory interface chips for data centers and PCs

  • by

SAN JOSE, Calif.–()–Rambus Inc. (NASDAQ: RMBS), a number one supplier of silicon IP and chips that make information quicker and safer, as we speak introduced the enlargement of its portfolio of DDR5 reminiscence interface chips with the addition of the Rambus SPD (serial presence detect) hub Y Temperature sensor, which enhances the {industry} main Rambus Recorder Clock Controller (RCD). DDR5 achieves larger reminiscence bandwidth and capability by using a brand new module structure with an expanded chipset. SPD hub and temperature sensors improve DDR5 twin inline reminiscence module (DIMM) system administration and thermal management to ship larger efficiency throughout the desired energy envelope for servers, desktops, and notebooks.

New ranges of DDR5 reminiscence efficiency place better significance on sign integrity and thermal administration for server and shopper DIMMs,” mentioned Sean Fan, chief working officer of Rambus. “With over 30 years of reminiscence subsystem design expertise, Rambus is ideally positioned to ship DDR5 chipset options that allow breakthrough bandwidth and capability for superior computing techniques.”

The robust collaboration between Intel and SPD ecosystem companions like Rambus delivers important chip options for Intel’s next-generation DDR5-based techniques, scaling the efficiency of servers, desktops, and laptops to new ranges.” Dr. Dimitrios Ziakas, Vice President of Reminiscence and IoT Applied sciences at Intel. “Our joint efforts to advance DDR5-based computing techniques are setting the stage for the development of Intel’s DDR5 throughout a number of generations and the following degree of efficiency for information facilities and shoppers.”

DDR5 offers a big efficiency increase for computing techniques,” mentioned Shane Rau, analysis vp for Computing Semiconductors at IDC. “Nonetheless, DDR5 reminiscence modules require new elements to operate, elements comparable to SPD hubs and temperature sensors are vital elements for shopper and server techniques.”

As a part of the Rambus shopper and server DDR5 reminiscence interface chipsets, the SPD hub and temperature sensor are mixed with the RCD to ship high-performance, high-capacity reminiscence options for DDR5 pc techniques. Each the SPD hub and temperature sensor are important elements in a reminiscence module that sense and report vital information for system configuration and thermal administration. The SPD hub is utilized in server and shopper modules, together with RDIMMs, UDIMMS, and SODIMMS, and the temperature sensor is designed for server RDIMMs.

Key options of the SPD Hub (SPD5118) embrace:

  • metwoC bus and I3C serial interface help

  • Superior reliability options

  • Expanded NVM house for customer-specific purposes

  • Low latency for quicker I3C bus speeds

  • Built-in temperature sensor

  • Meets or exceeds all JEDEC DDR5 SPD Hub (JESD300-5A) operational necessities

Key options of the temperature sensor (TS5110) embrace:

  • Precision thermal detection

  • metwoC bus and I3C serial interface help

  • Low latency for quicker I3C bus speeds

  • Meets or exceeds all JEDEC DDR5 temperature sensor working necessities (JESD302-1.01)
