Abstract
The throughput of the memory system is improved where error correction of data in a data stream is cryptographically processed with minimal involvement of any controller. To perform error correction when data from the memory cells are read, the bit errors in the data in the data stream passing between the cells and the cryptographic circuit are corrected prior to any cryptographic process performed by the cryptographic circuit. Preferably the error correction occurs in one or more buffers employed to buffer the data between the cryptographic circuit and the memory where latency is reduced by using multiple buffers.
