Latest Patents
Hiroshi Takayanagi holds a patent for an "Error detection and correction circuit and semiconductor memory." This invention involves a method where input data, having an integral multiple of 8 bits, is divided into symbols in units of b bits, where b is an integer between 5 and 7. An error detecting code is added in an error detection calculation circuit, followed by encoding, such as Reed Solomon (RS) encoding, which has an error correction capability of two or more symbols. This process ensures that data is recorded in a storage system. During reproduction, error correction is performed in units of symbols to retrieve data from storage, followed by error detection processing. This innovative approach allows for the recovery of data in an integral multiple of 8 bits, thereby providing a highly reliable storage system against soft errors that can occur in semiconductor memory.
