<P>PROBLEM TO BE SOLVED: To provide a memory device whose stored logic state is not erased even after the stop of power supply, and provide a signal processing circuit that can suppress power consumption by the stop of power supply due to the use of the memory device. <P>SOLUTION: A memory device includes a logic circuit having first and second nodes, a first memory circuit connected to the first node, a second memory circuit connected to the second node, and a precharge circuit connected to the first node, the second node, the first memory circuit, and the second memory circuit. At readout, the precharge circuit outputs a precharge potential to the first node and the second node. Each of the first and second memory circuits includes a transistor whose channel is formed in an oxide semiconductor film. <P>COPYRIGHT: (C)2013,JPO&INPIT |
