Abstract
A semiconductor device including a plurality of capacitance units connected in parallel between a first voltage and a second voltage. Each of the plurality of capacitance units includes: a capacitance element connected with the first voltage; and a capacitance disconnecting circuit connected between the second voltage and the capacitance element. The capacitance disconnecting circuit includes a non-volatile memory cell with a threshold voltage changed based on a change of a leakage current which flows from the capacitance element, and blocks off the leakage current based on a rise of the threshold voltage of the non-volatile memory cell when the leakage current exceeds a predetermined value.
