Abstract
A non-volatile semiconductor memory device that achieves downsizing as compared to conventional cases is disclosed. A non-volatile semiconductor memory device has a configuration in which a memory cell is disposed between a programming bit line and a reading bit line. The reading bit line provided between adjacent memory cells is shared by the adjacent memory cells. This configuration of the non-volatile semiconductor memory device, in which the reading bit line is shared by the adjacent memory cells, leads to reduction of the number of reading bit lines as compared to that in a conventional configuration, and further leads to reduction of the area of a control circuit and a sense amplifier circuit connected with the reading bit line, thereby achieving downsizing as compared to conventional cases accordingly.
