High-speed memristor programming system and method based on error correction code

The invention belongs to the technical field of memories, and particularly relates to a high-speed memristor programming system and method based on error correction codes. The system comprises a coding circuit used for performing ECC coding on input data, a writing circuit used for writing on-chip or external data and check bits obtained by the coding circuit into a memory, a memristor array used for storing data information and check bit information obtained by ECC coding, a reading circuit used for reading out data in the memristor array, and a storage circuit used for storing the data information and the check bit information obtained by ECC coding. The decoding circuit is used for performing ECC decoding operation on the data read by the reading circuit; according to the invention, the error correction code is adopted, the writing operation is carried out by taking relatively short writing operation time as a reference, a small amount of writing errors are allowed to occur in a fault-tolerant range during
