Patent attributes
A semiconductor device includes a first chip having a first via and a second via through the first chip; and a second chip provided on the first chip and having a third via and a fourth via through the second chip. The first chip includes: a first logical operation circuit configured to perform a first logical operation (NOT) on a first address input signal to output a first address output signal to the second chip through the first via; a second logical operation circuit connected to the first logical operation circuit, the second logical operation circuit being configured to perform a second logical operation (XOR) on a second address input signal and the first address output signal to output a second address output signal to the second chip through the second via; and a first activation circuit connected to the second logical operation circuit, the first activation circuit being configured to activate the first chip based on at least the second address output signal.
