Abstract
A semiconductor memory apparatus is disclosed having a dual open bit line structure In the dual open bit line structure, bit lines or bit line bars are each arranged side by side in adjoining cell mats. The semiconductor memory apparatus includes a coupling control section connected between at least one pair of adjoining bit lines or at least one pair of adjoining bit line bars and is driven by a bit line equalize signal. The coupling control section prevents a coupling phenomenon from occurring between pairs of bit lines and bit line bars.
