Error corrector with a high use efficiency of a memory

摘要

An error corrector with a high use efficiency of a memory includes a memory, a bus device, an input buffer and an error correction module. The memory stores data. The bus device controls a memory access. The input buffer receives and temporarily stores a coded blockcode data, and writes the coded blockcode data in the memory through the bus device. The error correction module reads the coded blockcode data in the memory through the bus device and decodes it in rows and columns to thereby obtain decoded data and check bytes. The error correction module writes the decoded data in the memory through the bus device and discards the check bytes.
