Highlights:
- Introduces SPD Hub and Temperature Sensor as part of server and
client DDR5 memory module chipsets
- Complements industry-leading DDR5 RCD delivering
state-of-the-art bandwidth and capacity
- Enables enhanced system management and thermal control for
improved TCO
Rambus Inc. (NASDAQ: RMBS), a premier chip and silicon IP
provider making data faster and safer, today 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 industry-leading 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 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 new performance levels of DDR5 memory place an increased
premium on signal integrity and thermal management for server and
client DIMMs,” said Sean Fan, chief operating officer at Rambus.
“With over 30 years of memory subsystem design experience, Rambus
is ideally positioned to deliver DDR5 chipset solutions which
enable breakthrough bandwidth and capacity for advanced computing
systems.”
“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.”
“DDR5 provides a significant increase in performance for
computing systems,” said Shane Rau, research vice president,
Computing Semiconductors at IDC. “However, DDR5 memory modules
require new components to function, components like SPD hubs and
temperature sensors are important components for client and server
systems.”
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)
Availability and Additional Information
The Rambus SPD Hub and Temperature Sensor are both available
today. For additional information, please visit
