发明名称 Nonvolatile semiconductor memory device and nonvolatile semiconductor memory system
摘要 A memory may include word lines; bit lines; cells provided corresponding to intersections between the word lines and the bit lines; sense amplifiers detecting data; a column decoder selecting a certain bit line for the sense amplifiers to output read data or receive write data; a row decoder configured to select a certain word line; a charge pump supplying power to the sense amplifiers, the column decoder, and the row decoder; a logic circuit controlling the sense amplifiers, the column decoder, and the row decoder based on an address selecting the memory cells; a first power source input applying a voltage to the logic circuit; and a second power source input applying a voltage higher than a voltage of the first power source input to the charge pump, and to supply power to the charge pump at least at a data reading time and a data writing time.
