Abstract
A semiconductor memory device is provided that uses a single wordline to access both storage cells of a so-called twin cell. A memory device comprises a plurality of wordlines and a plurality of bitlines in an array, with a plurality of storage cells at certain intersections of wordlines and bitlines. A plurality of sense amplifiers are provided, each of which is connected to at least a first pair of bitlines to detect a voltage difference on the bitlines caused by the charge from a twin storage cell comprised of first and second storage cells at the intersection of a single wordline with said first pair of bitlines, respectively. As a result, each cell of a twin storage cell can be accessed with a single wordline.
