    Abstract: A charge pump device and an operating method thereof are proposed. The charge pump device is composed of a plurality of stages of charge transfer units and an output unit that are cascaded together. Each stage of the charge transfer units includes a first node for input, a second node for output, a first circuit and a first capacitor. The first node or the second node is biased at a bias provided for the first circuit. Thereby, the first capacitors of the odd-numbered stage and the even-numbered stage of charge transfer units can respectively receive two clock signals that are mutually opposite in phase for complementary switching operating. Collocated with the switching of the output unit, an output voltage with a high negative level can be generated.

    Abstract: A non-self aligned non-volatile memory structure includes a semiconductor substrate; a first gate insulation layer on said semiconductor substrate; a floating gate on first gate insulation layer; two doped regions in said semiconductor substrate, which are respectively on two sides of said first gate insulation layer, and adjoining said first gate insulation layer; a second gate insulation layer on said floating gate; and a control gate on said second gate insulation layer. Width of said control gate on said floating gate is less than that of said floating gate, and width of said control gate not on said floating gate is equal to or greater than width of said floating gate. Through the two non-self aligned gates, the non-volatile memory does not need to meet the requirement of gate line-to-line alignment, thus reducing complexity and cost of manufacturing process.
