Rambus Inc. announced the expansion of its DDR5 memory interface chip portfolio with the addition of the Rambus SPD (Serial Presence Detect) Hub and Temperature Sensor, complementing the Rambus Registering Clock Driver (RCD).

DDR5 achieves greater memory bandwidth and capacity by employing a new module architecture with an expanded chipset. The SPD Hub and Temperature Sensors are designed to improve DDR5 Dual Inline Memory Module (DIMM) system management and thermal control to deliver higher performance within the desired power envelope for servers, desktops, and laptops.

“The strong collaboration between Intel and SPD ecosystem partners like Rambus, delivers critical chip solutions for Intel’s next generation DDR5-based systems, scaling server, desktop and laptop performance to new levels,” said Dr. Dimitrios Ziakas, VP of Memory and IO Technologies at Intel. “Our joint efforts to advance DDR5-based computing systems is setting the stage for Intel’s DDR5 advance over multiple generations and the next level of performance for data centers and consumers.”

Part of the Rambus server and client DDR5 memory interface chipsets, the SPD Hub and Temperature Sensor combine with the RCD to deliver high-performance, high-capacity memory solutions for DDR5 computing systems. Both the SPD Hub and Temperature Sensor are critical components on a memory module that sense and report important data for system configuration and thermal management. The SPD Hub is used in both server and client modules, including RDIMMs, UDIMMS and SODIMMS, and the temperature sensor is designed for server RDIMMs.

Key features of the SPD Hub (SPD5118) include:

• I²C and I3C bus serial interface support
• Advanced reliability features
• Expanded NVM space for customer-specific applications
• Low latency for fastest I3C bus rates
• Integrated temperature sensor
• Meets or exceeds all JEDEC DDR5 SPD Hub operational requirements (JESD300-5A)

Key features of the Temperature Sensor (TS5110) include:

• Precision thermal sensing
• I²C and I3C bus serial interface support
• Low latency for fastest I3C bus rates
• Meets or exceeds all JEDEC DDR5 Temperature Sensor operational requirements (JESD302-1.01)

The Rambus SPD Hub and Temperature Sensor are both available today.
