Microchip Introduces SMC 2000, CXL Memory Controller For Data Centers

Last month’s microchip was introduced storage controller its new, SMC 2000, in the world. is CXL Type 3 memory controllerMicrochip SMC 2000 supports both DDR4 and DDR5 memory, allowing the CPU, GPU and SoC to take advantage of the CXL interface (Calculate express link) to connect and use both DDR4 memory and DDR5 memory. Microchip claims to be able to add the SMC 2000 bandwidth memory per Vein and increase storage capacity per Vein as well as reducing the total cost of ownership (total ownership cost) in the Alias ​​data center data center.

Microchip added that currently the number of main memory channels supported by a CPU or SoC is limited. Increasing the number of main memory channels also comes into question. The microchip SMC 2000 could be the answer to these limitations, for example for AI workloads (artificial intelligence) including ML (machine learning), data analysisand Cloud which takes a lot of memory to run better in the data center.

There are two variants of the SMC 2000 introduced by Microchip, namely the SMC 2000 16×32G and the SMC 2000 8×32G. The main difference between the Microchip SMC 2000 16×32G and the Microchip SMC 2000 8×32G is the number of lanes alias roadway supports. The Microchip SMC 2000 16×32G supports CXL 1.1/2.0 up to x16, while the Microchip SMC 2000 8×32G supports CXL 1.1/2.0 up to x8. Meanwhile, 32G refers to the supported CXL speed, which is 32 GT/s. Microchip also mentions that SMC 2000 completes the portfolio Serial attached memory controllershe and is Serial attached memory controller its first CXL-based.

“Microchip is excited to introduce the device Serial memory controller our first CXL-based launch,” said Pete Hazen, corporate vice president of Microchip’s Data Center Solutions business. “We identified CXL as a disruptive technology from the start and are an integral part of defining the standard. Microchip’s continued presence in the storage infrastructure market underscores our commitment to improving the performance and efficiency of various SoC applications to support the increasing storage requirements of high-performance data center applications.”

“The CXL Consortium was formed with a vision to provide an open standard for the industry that will accelerate the performance of the next generation of data centers,” said Siamak Tavallaei (President, CXL Consortium). “We are pleased that Microchip, a major contributor to the CXL Consortium, is delivering a CXL solution that enables a new ecosystem for heterogeneous high-performance computing.”

Microchip goes on to say that the SMC 2000 supports DDR4 and DDR5 according to the JEDEC standard. In addition, Microchip claims the SMC 2000 16×32G as controller with 16 lanes and a speed of 32 GT/s supporting the highest capacity in the industry. Microchip also mentions that the SMC 2000 supports 16×32G dual-channel DDR4-3200 and dual-channel DDR5-4800. However, Microchip has not specified the highest DDR4 and DDR5 frequencies supported by the SMC 2000 8×32G.

As usual, there are also development tools. Regarding availability, Microchip only said the availability of the SMC 2000 16×32G. According to Microchip, the SMC 2000 16×32G will go into sampling for selected consumers in the third quarter of 2022.
