The SMC 1000 8x25G allows central processing units (CPUs) and other computer-centric system-on-chips (SoCs) to use four times the memory channels of parallel attached DDR4 dynamic random access memory (DRAM) in the same package footprint. Microchip said the memory allows these compute-intensive platforms to have higher memory bandwidth with low latency.

The serial memory controller interfaces to the CPU via 8 bit open memory interface (OMI)-compliant 25 Gbps lanes and bridges to memory via a 72 bit DDR4 3200 interface. This results in a reduction in the required number of host CPU or SoC pins per DDR4 memory channel, allowing for more memory channels and increasing the memory bandwidth.

Other features include a design that delivers less than 4 ns incremental latency over a traditional integrated DDR controller with load reduced dual in-line memory module (LRDIMM). This results in OMI-based dual in-line memory module (DDIMM) products having virtually identical bandwidth and latency performance to comparable LRDIMM products, Microchip said.
