Abstract: An occupant protection device which can protect an occupant without delay is provided. An image taken by an imaging device is analyzed to judge whether there is an object approaching the subject car. In the case where a collision between the object and the subject car is judged to be inevitable, an airbag device is activated before the collision, whereby the occupant can be protected without delay. By using selenium for a light-receiving element of the imaging device, an accurate image can be obtained even under low illuminance. Imaging in a global shutter system leads to an accurate image with little distortion. This enables more accurate image analysis.

Abstract: An imaging device capable of image processing is provided. The imaging device has an image recognition function. In the imaging device, cells have a function of acquiring imaging data and a function of retaining weight data. Among the cells arranged in a matrix, some of the cells acquire imaging data and the rest of the cells retain weight data. Then, arithmetic operation is performed using the imaging data and the weight data. For example, all the imaging data can be subjected to arithmetic operation where products of the imaging data and the weight data are calculated and the sum of the calculated products is calculated. That is, product-sum operation can be performed. When an arithmetic operation result is captured by a neural network such as a convolutional neural network (CNN) or the like, the additional function can be used because image processing can be performed on the imaging data.

Abstract: A low-power memory device in which a NAND flash memory and a controller are connected to each other with a short wiring, the controller and a cache memory are connected to each other with a short wiring, and signal transmission delay is small is provided. For example, the NAND flash memory is formed using a Si transistor formed with a single crystal silicon substrate. Since an OS transistor can be formed by a method such as a thin-film method, the cache memory formed using the OS memory can be stacked over the NAND flash memory. When the NAND flash memory and the cache memory are formed in one chip, the NAND flash memory and the controller can be connected to each other with a short wiring, and the controller and the cache memory can be connected to each other with a short wiring.
