Summary:SEMICONDUCTOR MEMORY DEVICE ABSTRACT OF THE DISCLOSURE A semiconductor memory device of a charge-storage type in which information can be erased by strong ultraviolet light is disclosed. The device comprises at least one dummy bit line connected to dummy cells incorporated with main memory cells and at least one compensating circuit for detecting the potential of the dummy bit line. The compen-sating circuit supplies compensating currents to bit lines connected to the main memory cells, responsive to the change of he potential of the dummy bit line.
