DDR5 ecosystem grows with memory interface components

DDR5 chipset solutions require memory interface solutions that can effectively handle signal integrity and thermal management for data center servers, desktops, and laptops. Rambus says it has answered the call by expanding its portfolio of DDR5 memory interface chips with a serial presence detection (SPD) hub and temperature sensors.

This complements the company’s Record Clock Driver (RCD) technology and should improve system management and thermal control of the DDR5 Dual Inline Memory Module (DIMM), ensuring higher performance in the desired power envelope. The SPD hub and temperature sensor on a memory module detect and report important data for system configuration and thermal management.

The SPD hub is used in both server and client modules, including Registered DIMMs (RDIMMs), Unbuffered DIMMs (UDIMMs), and Small Outline DIMMs (SODIMMs). On the other hand, the temperature sensor is designed for server RDIMMs.

Big data applications put tremendous pressure on data center memory systems for increased performance and capacity. This, in turn, transforms the memory architecture of servers supporting memory-intensive cloud deployments and artificial intelligence (AI) applications. Here, DDR5 achieves higher bandwidth and memory capacity by using a new module architecture with an extended chipset.

However, DDR5 memory modules require new components for client and server systems. This includes memory interface devices such as the RCD, SPD hub, and temperature sensor. These interface devices are crucial in the ability of the DDR5 chipset to enable breakthrough bandwidth and capacity for advanced computing systems.
