摘要： A secure memory card with encryption capabilities comprises various life cycle states that allow for testing of the hardware and software of the card in certain of the states. The testing mechanisms are disabled in certain other of the states thus closing potential back doors to secure data and cryptographic keys. Controlled availability and generation of the keys required for encryption and decryption of data is such that even if back doors are accessed that previously encrypted data is impossible to decrypt and thus worthless even if a back door is found and maliciously pried open.

摘要： 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 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.
