Abstract: A semiconductor device includes: a first cell; a second cell; a first match line and a second match line; a first search line pair, first data being transmitted through the first search line pair; a second search line pair, second data being transmitted through the second search line pair; a first logical operation cell connected to the first search line pair and the first match line, and configured to drive the first match line based on a result of comparison between information held by the first and second cells and the first data; and a second logical operation cell connected to the second search line pair and the second match line, and configured to drive the second match line based on a result of comparison between information held by the first and second cells and the second data.

Abstract: An image sensor device includes a plurality of pixel cells arranged in a matrix in a pixel array, and a timing control circuit that controls read-out of pixel information from the plurality of pixel cells. Each of the plurality of pixel cells includes a photodiode, a transfer transistor provided between the photodiode and a floating diffusion, a node reset transistor provided between a power supply terminal and the floating diffusion, a read-out capacitor whose one end is connected to the power supply terminal, a capacitor reset transistor provided between another end of the read-out capacitor and the floating diffusion, an amplification transistor that amplifies a voltage generated based on electric charges accumulated in the floating diffusion, and a selection transistor provided between the amplification transistor and a read-out line.
