Abstract
A decoder for decoding a binary symmetry-invariant product code includes a data array having orthogonal first and second dimensions. The data array is configured to access a binary symmetry-invariant product code buffered therein along only the first dimension. The decoder also includes an error storage array for storing error locations and a first correction circuit configured to detect and correct errors in data accessed from the data array along the first dimension and to store error locations along the second dimension in the error storage array. The first correction circuit determines the error locations based on data symmetry of the symmetry-invariant product code. The decoder also includes a second correction circuit that, prior to receipt by the first correction circuit of data accessed from the data array along the first dimension, corrects the data accessed from the data array based on the error locations stored in the error storage array.
