    摘要: A semiconductor device capable of preventing a sharp variation in current consumption in neural network processing is provided. A dummy circuit outputs dummy data to at least one or more of n number of MAC circuits and causes the at least one or more of n number of MAC circuits to perform a dummy calculation and to output dummy output data. An output-side DMA controller transfers pieces of normal output data from the n number of MAC circuits to a memory, by use of n number of channels, respectively, and does not transfer the dummy output data to the memory. In this semiconductor device, the at least one or more of n number of MAC circuits perform the dummy calculation in a period from a timing at which the output-side DMA controller ends data transfer to the memory to a timing at which the input-side DMA controller starts data transfer from the memory.

    摘要: Reliability and performance of a semiconductor device are improved. First, a first mask pattern is formed on the semiconductor substrate in each of first to third regions. Next, a second mask pattern made of a material that is different from a material configuring the first mask pattern is formed on a side surface of the first mask pattern and on the semiconductor substrate in each of the first to third regions. Next, by an anisotropic etching process performed to the semiconductor substrate, a plurality of fins protruding from the recessed upper surface of the semiconductor substrate are formed. In the manner, fins each having a different structure from that of a fin in the first region can be formed in the second and third regions.
