Renesas Electronics Corporation offers a new high-speed, low-power DDR5 data buffer for data centre, server, and high-performance workstation applications.
Advances over the last few years in real-time analytics, machine learning, AI, HPC, and other memory and bandwidth-hungry applications have feed an explosive growth in server memory bandwidth needs. The new JEDEC-compliant DDR5 data buffer 5DB0148 from the company facilitates significantly higher speeds and lower latency for LRDIMMs that have evolved to be the cornerstone memory technology for this new class of applications. The first generation of DDR5 LRDIMMs based on the company's components allows a bandwidth increase of more than 35% over DDR4 LRDIMMs operating at 3200MT/s.
“As the industry’s complete DDR5 solution provider, we are working closely with customers and ecosystem partners to launch a vastly expanded portfolio of memory solutions into production,” said Rami Sethi, vice president, Data Center Business Division at Renesas. “Our DDR5 data buffers are critical to enabling high-performance DRAM solutions such as LRDIMMs, alternative high-density modules and heterogeneous memory solutions, all of which empower a new generation of high-performance computing applications.”
The DDR5 Data Buffer maximises channel eye-opening for systems that are heavily loaded via a combination of data alignment, capacitive load reduction, and signal recovery techniques. This enables server motherboards with an extensive number of memory channels and slots and complex routing topologies to operate at maximum speed, even when populated with high-density memory. Also, improvements in the DDR5 modules definition provide for lower power supply voltages (1.1V vs 1.2V in DDR4), on-DIMM voltage regulation, and execution of advanced control plane architectures with the usage of the SPD Hub and modern control bus communications such as I3C.
