ERROR-CORRECTING FUNCTION CHECKING CIRCUIT, ERROR-CORRECTING FUNCTION CHECKING METHOD, COMPUTER PROGRAM THEREFOR, AND STORAGE DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide an ECC function checking circuit which easily, efficiently checks an ECC function, and also provide an ECC function checking method, a computer program therefor and a storage device. PSOLUTION: The ECC function checking circuit checks the ECC function of an ECC circuit which corrects errors of data in a storage device. When the ECC function is checked, pseudo-errors are generated by a data inversion circuit which inverses the prescribed bits of data read from the storage device. To the data inversion circuit, instructions for data inversion are given by data written to the storage device. PCOPYRIGHT: (C)2010,JPO&INPIT
