|1. (WO2018122658) SEMICONDUCTOR DEVICE|
|Applicants:||SEMICONDUCTOR ENERGY LABORATORY CO., LTD.
A semiconductor device comprises a lookup table comprising a memory, a first circuit and a second circuit. The first circuit receives a first signal and a second signal. The second circuit receives a third signal. When the first circuit receives the third signal, the first circuit sends a fourth signal and a fifth signal. When the lookup table receives the fourth signal and the fifth signal, the lookup table sends a sixth signal and a seventh signal. When the second circuit receives the sixth signal and the seventh signal, the second circuit sends an eighth signal. The first circuit receives the eighth signal, the first circuit sends ninth signal. The sixth signal and the seventh signal are generated from data stored in the memory.
