Patent attributes
A nonvolatile semiconductor memory device comprises: a bit line; a source line; a memory string having a plurality of electrically data-rewritable memory transistors connected in series; a first select transistor provided between one end of the memory string and the bit line; a second select transistor provided between the other end of the memory string and the source line; and a control circuit configured to control a read operation. A plurality of the memory strings connected to one bit line via a plurality of the first select transistors. During reading of data from a selected one of the memory strings, the control circuit renders conductive the first select transistor connected to an unselected one of the memory strings and renders non-conductive the second select transistor connected to unselected one of the memory strings.
