Abstract
One embodiment provides a programmable logic switch in which a first nonvolatile memory and a second nonvolatile memory are formed in the same well, and in which to change the first nonvolatile memory from an erased state to a written state and leave the second nonvolatile memory being in the erased state, a first write voltage is applied to a first line connected with gate electrodes of the first and second nonvolatile memories, a second write voltage is applied to a second line connected to a source in the first nonvolatile memory, and a third write voltage lower than the second write voltage is applied to a fourth line connected to a source of the second nonvolatile memory.
