Abstract:
1. A programmable logic switch comprising: a first nonvolatile memory having: a second nonvolatile memory having: a first line connected to the first gate electrode and to the second gate electrode; a second line connected to the first source; a third line connected to the first drain and to the second drain; a fourth line connected to the second source; a substrate electrode through which a substrate voltage is applied to a well, the first nonvolatile memory and the second nonvolatile memory being formed in the well; one or more first logic transistors connected to the third line, each first logic transistor being connected to the third line at a gate electrode thereof; and a controller configured to connect, 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, wherein the controller connects the first write voltage to the first line before connecting the second write voltage to the second line.
