ABSTRACT:
A system and method for enhanced read performance of a memory storage system is disclosed. The storage system includes a first memory controller. At least one first channel of a plurality of memory modules couples to the first memory controller. At least one memory module in the at least one first channel can return data sought in a read request, if present, to the first memory controller without sending the data through each memory module in the at least one first channel. The storage system also includes a second memory controller coupled to at least one second channel of a plurality of memory modules. At least one memory module in the at least one second channel can return data sought in a read request, if present, to the second memory controller without sending the data through each memory module in the at least one second channel. The at least one second channel contains an inverse mirror copy of data stored on the first channel.
