ASSOCIATIVE MEMORY AND DATA PROCESSOR

摘要

PURPOSE:To provide a technology to surely relieve an associative memory or an LSI including this associative memory. CONSTITUTION:A memory line valid/invalid flag generating part 103 and an AND circuit 111 serve as the means which invalidate the deciding result of an address comparing part 102 based on the information on a defective part. Even if the presence is decided for such an address that is inputted for a searching purpose, the operation is limited to read the data out of a data storage means by invalidating such deciding result. Thus it is possible to relieve an associative memory including such a defect that cannot be relieved in a redundant constitution.
