Overview
The iMC unit contains four controllers. Up to four channels can be operated
independently or DDR Channels behind Intel C102/C104 Scalable Memory Buffer can
be paired for lockstep operation. The DRAM controllers share a common address
decode and DMA engines for RAS features.

Configuration registers may be per channel or common. Each DRAM controller has a
scheduler, write and read data paths, ECC logic and auxiliary structures.
