Overview of the SMC 1000 8x25G: OMI to DDR4 Memory Controller
summary
Microchip’s SMC1000 is a serial memory controller that converts 8x25G OMI into native DDR4, packing four times the channels into ~34 signals versus ~150 DDR pins and supporting DDR4 at up to 3200 MT/s and up to 256 GB per controller. It implements OpenCAPI/OMI stack, a MIPS management core, hardware root of trust, single- and double-symbol ECC with scrub and chip‑kill, dynamic lane scaling (8/4/2 lanes), persistent‑memory hooks, a 17×17 mm package, and measures 3.94 ns extra loaded latency versus LRDIMM.
