  • Patent number: 9711235
    Abstract: A nonvolatile memory device includes a voltage generating circuit configured to generate voltages applied to word lines corresponding to a selected memory block among memory blocks. The voltage generating circuit includes voltage source lines having linear voltages, a first voltage generating unit configured to generate a first voltage and apply the generated first voltage to a first voltage source line among the voltage source lines, a second voltage generating unit configured to generate a second voltage and apply the generated second voltage to a second voltage source line among the voltage source lines, and a linear voltage generator having a resistor string connected between the first voltage source line and the second voltage source line. At least one of the voltage source lines has a voltage distributed between the first voltage and the second voltage.
