Abstract
A scalable memory controller for use in connection with error correction code is provided. According to the invention, the channels of the controller are interconnected to a plurality of parity engines and associated cache memories using a switched fabric architecture. A processor is provided for allocating operations requiring access to the parity engines or cache memories. By providing multiple parity engines and cache memories, error correction syndrome values can be calculated in parallel. The performance of the controller can be selectively scaled by providing a greater or lessor number of parity engines and associated cache memories. Furthermore, by utilizing a switched fabric internal architecture, data transfers between the internal components of the controller can be conducted simultaneously.
