Abstract
Electronic memory apparatus, and method for deactivating redundant bit lines or word lines An electronic memory apparatus () having a memory cell array (), a column address decoding unit () for decoding a column addressing signal () and for actuating an addressed bit line in the memory cell array (), a column redundancy activation unit () for activating a redundant bit line when a currently used bit line has been determined to be faulty during testing of the memory apparatus (), a row address decoding unit () for decoding a row addressing signal () and for actuating an addressed word line in the memory cell array (), and a row redundancy activation unit () for activating a redundant word line when a currently used word line has been determined to be faulty during testing of the memory apparatus (). A column deactivation unit deactivates unused, redundant bit lines and those bit lines which have been determined to be faulty during testing of the memory apparatus, and a row deactivation unit () deactivates unused, redundant word lines and those word lines which have been determined to be faulty during testing of the memory apparatus ().
