Abstract: A non-volatile semiconductor memory device has a NAND string, in which multiple memory cells are connected in series. A read procedure is performed for a selected memory cell in the NAND string on the condition that the selected memory cell is applied with a selected voltage while unselected memory cells are driven to be turned on without regard to cell data thereof. In the read procedure, a first read pass voltage is applied to unselected memory cells except an adjacent and unselected memory cell disposed adjacent to the selected memory cell, the adjacent and unselected memory cell being completed in data write later than the selected memory cell, and a second read pass voltage higher than the first read pass voltage is applied to the adjacent and unselected memory cell.

Each of the transfer transistors includes: a gate electrode formed on a semiconductor substrate via a gate insulation film; and diffusion layers formed to sandwich the gate electrode therebetween and functioning as drain/source layers. Upper layer wirings are provided above the diffusion layers and provided with a predetermined voltage to prevent depletion of the diffusion layers at least when the transfer transistors become conductive.
