ABSTRACT:
A high density semiconductor memory device of the present invention provides equalizing circuits for equalizing isolation signals that control a connection between bit lines and sense amplifiers. During a row precharge operation, the equalizing circuits, in response to block selection signals, equalize the isolation signals for transferring signals. As a result, this shortens the required row precharge time.
