The DMH facilitates memory devices isolation and correction for X4 memory geometries. The
DMH facilitates this by ensuring that no data bit is mapped onto the same SDRAM device as any
of its ECC bits. The mapping allows the Scalability Node Controller (SNC) to organize data and
ECC symbols in an arrangement that allows ECC to reconstruct all four bits of data associated with
a failed SDRAM device.
Supported Memory Configurations
The DMH supports 128 Mb, 256 Mb, 512 Mb, and 1 Gb
technologies in 4-bank, X4 and X8 geometries, on 184-pin DIMMs.
