Title:
半導体装置
Document Type and Number:
Japanese Patent JP4021283
Kind Code:
B2
Abstract:
A semiconductor device that has the function of initializing an intern circuit. A starter sign generation circuit outputs a starter sign for initializing the intern circuit in the semiconductor device on the basis of input power supply voltage. A latch circuit holds and outputs the starter sign. A shutoff circuit shuts off input of the power supply voltage to the starter sign generation circuit when the starter sign is output. That is to say, the starter sign output on the basis of the power supply voltage is held by the latch circuit and the power supply voltage input to the starter sign generation circuit is shut off. As a result, consumption of power is reduced.
