Optimizing Capacity, Connectivity and Capability of the Cloud
At Rambus, we create cutting-edge semiconductor and IP products, spanning memory and interfaces to security, smart sensors and lighting.
Memory Interface Chips
Providing memory bandwidth and capacity to unleash the power of multicore processors
Tackling advanced workloads requires ever increasing levels of memory bandwidth and capacity. With over three decades of high-performance memory expertise, Rambus delivers the most advanced memory interface chipset solutions.
For data center applications, the Rambus Memory Interface Chip portfolio includes DDR5 RDIMM and MRDIMM chipsets for the latest generation DDR5-based servers as well as those slated for release in the years ahead. For DDR4-based servers, Rambus offers DDR4 memory interface chips that enable the highest bandwidth and capacity RDIMMs supported by the DDR4 standard.
As advanced technologies honed in the data center proliferate to the client space, the Rambus DDR5 Client DIMM Chipset enables client DIMMs (CSODIMMs and CUDIMMs) to deliver new levels of memory performance for PC desktops and laptops.

The Rambus DDR5 Server DIMM chipset includes the DDR5 Registering Clock Drivers (RCD), Power Management ICs (PMICs), Serial Presence Detect Hubs (SPD Hub) and Temperature Sensors (TS) for DDR5 RDIMMs. For Multiplexed Rank DIMMs (MRDIMMs), Rambus offers DDR5 Multiplexed Registering Clock Drivers (MRCD) and Multiplexed Data Buffers (MDB) as well as PMIC, SPD Hub and TS chips. These market-leading solutions deliver performance of up to 8000 MT/s (RDIMM) and 12800 MT/s (MRDIMM) supporting current and future data center servers.
The Rambus DDR5 Client DIMM Chipset includes the DDR5 Client Clock Driver (CKD) and Serial Presence Detect Hubs (SPD Hub). These solutions enable state-of-the-art data rates of up to 7200 MT/s to deliver breakthrough performance in next-generation AI PCs.
The Rambus DDR4 Server DIMM chipset includes the DDR4 Registering Clock Driver (RCD), Data Buffer (DB) and Non-Volatile Registering Clock Driver (NVRCD). These solutions deliver performance levels up to 3200 MT/s for current DDR4 RDIMMs.
DDR5 Memory Enables Next-Generation Servers
An exponential rise in data volume, and the rapid increase of advanced workloads like AI/ML training, requires constant innovation in all aspects of computing. Yet given the broad infrastructure implications, main memory technology changes infrequently, once every 6 or 7 years. The transition to DDR5 is a watershed industry event as it will be the main memory solution in servers for the rest of this decade.
