Abstract
A semiconductor device includes first and second voltage control lines for a first memory block and third and fourth voltage control lines for a second memory block, for driving gate lines for memory transistors; a first decoder driving the first and third voltage control lines; a second decoder driving the second and fourth voltage control lines; and a control circuit controlling a voltage for the first and second decoders. The control circuit supplies a first voltage and a second voltage lower than the first voltage to the first decoder and a third voltage between the first and second voltages, and the second voltage to the second decoder, before writing operation; and supplies the first voltage and the third voltage to the first decoder and a fourth voltage between the third and second voltages, and a fifth voltage lower than the second voltage to the second decoder, in the writing operation.
