Patent number: 7580293Abstract: A programmable non-volatile semiconductor memory device includes a select gate 3, arranged in a first region on a substrate, a floating gate 6 arranged in a second region neighboring to the first region, a first diffusion region 7 provided in a third region neighboring to the second region, a control gate 11 arranged on the floating gate 6, and a driving circuit 22 adapted for controlling voltages applied to the substrate 1 (well 1a), select gate 3, first diffusion region 7 and control gate 11. The driving circuit performs control so that, during erasure operation, voltages applied to select gate 3 and the control gate 11 are negative, with the remaining voltage, applied to the substrate 1 (or well 1a), being positive. The device permits erasure operation at a lower voltage.Type: GrantFiled: January 31, 2007Date of Patent: August 25, 2009Assignee: NEC Electronics CorporationInventors: Kohji Kanamori, Kenichi Kuboyama
