Abstract: A non-volatile memory device that includes a floating gate element, a control coupling element, an erase coupling element and a select gate element is provided. The floating gate element includes a floating gate layer. The control coupling element receives a control voltage and couples the control voltage to the floating gate layer such that the floating gate element performs read or write operation according to the control voltage, a word select voltage and a bit select voltage. The erase coupling element receives an erase voltage and couples the erase voltage to the floating gate layer such that the floating gate element performs erase operation according to the erase voltage. The select gate element is electrically coupled to the floating gate element and generates the word select voltage according to a word line driving voltage and a source line driving voltage.

Abstract: A non-volatile memory device is provided. The non-volatile memory device includes a substrate area, two storage units, a spacer structure and two control units. The storage units include two anti-fuse gates each having a gate dielectric layer between the anti-fuse gate and the substrate area and two diffusion areas. The spacer structure is formed on the substrate area and between the two anti-fuse gates and contacts thereto. Each of the diffusion areas is a first doping area doped with a first type dopant contacting one of the two anti-fuse gates. Each of the control units includes a select gate formed on the substrate area and a second doping area. A first side of the select gate contacts one of the diffusion areas of the storage unit. The second doping area is doped with the first type dopant and contacts a second side of the select gate.
