Abstract
A semiconductor device includes a main circuit and a peripheral circuit inputting/outputting a signal from/to the main circuit, the main circuit including: a memory cell array; a sense amplifier; a first output holding circuit holding the read data output from the sense amplifier; a second output holding circuit receiving the read data as its input output from the first output holding circuit; and a delay circuit outputting a delay signal for activating the second output holding circuit to be later than the first output holding circuit. The delay circuit includes an element applying a load capacitance to a wiring of the delay signal. A power-supply voltage being a first voltage is supplied to the memory cell array, the sense amplifier and the first output holding circuit. A power-supply voltage being a second voltage is supplied to the delay circuit, the second output holding circuit and the peripheral circuit.
