1. A method, comprising: partitioning a parity component into a plurality of portions, the parity component based on a memory space designated for error correction such that a plurality of parity components define a context; storing corresponding portions of the parity components in a first memory area, the first memory area responsive to a parity operation for computing a parity value for the corresponding portions, a parity value for the context based a plurality of parity components; applying the parity operations to the portions stored in the first memory area; and iteratively replacing the portions with other portions from a second memory area for applying the parity operation to each of the portions until all portions of the parity component have undergone the parity operation, the second memory area sufficiently large for storing the entire context.
