Abstract
In a semiconductor device, an arithmetic circuit of a chip on a first stage performs a predetermined arithmetic operation on an input N-bit (N=4) selection signal. Similarly, an arithmetic circuit of each of chips on second and subsequent stages among chips on a total of M stages (M>N≥2, M=16) performs a predetermined common arithmetic operation on an operation result of the arithmetic circuit of the chip on the preceding stage. A determination circuit provided in each chip performs a predetermined common logic operation on a bit string of the N-bit signal, which is the operation result of the corresponding arithmetic circuit, thereby determining whether it is the chip selected by the selection signal.
