Abstract
A semiconductor device having a novel structure is provided. The semiconductor device includes a CPU and an accelerator. The accelerator includes a first memory circuit and an arithmetic circuit. The first memory circuit includes a first transistor. The first transistor includes a semiconductor layer containing a metal oxide in a channel formation region. The arithmetic circuit includes a second transistor. The second transistor includes a semiconductor layer containing silicon in a channel formation region. The first transistor and the second transistor are provided to be stacked. The CPU includes a CPU core including a flip-flop provided with a backup circuit. The backup circuit includes a third transistor. The third transistor includes a semiconductor layer containing a metal oxide in a channel formation region.
