MEMORY READ-CHANNEL WITH SELECTIVE TRANSMISSION OF ERROR CORRECTION DATA |
摘要 |
A memory read-channel is provided with selective transmission of error correction data. The disclosed read-channel improves throughput and reduces power consumption when error correction codes are unnecessary. The data read from a memory device comprises user data, error detection data and error correction data. In one embodiment, the error detection data is evaluated to determine if there is a data error; and the error correction data is transmitted only if a data error is detected. In another variation, the error detection data is evaluated during data transmission to determine if there is a data error and the transmission is suspended if a data error is detected. Typically, the error detection data comprises a cyclic redundancy check and the error correction data comprises parity check data.
