Abstract
A semiconductor device includes a logic chip having a prescribed function and a memory chip for storing data are mounted in a common package. The logic chip and memory chip are connected through memory access terminals, which are a control signal terminal, address terminal, and data terminal. The logic chip has a logic circuit having prescribed functions and a memory chip testing circuit for performing operation tests on the memory chip. The logic chip also has a selector-output circuit for selecting a memory access signal from the logic circuit and a memory testing access signal from the memory chip testing circuit to output the selected signal to the memory access terminal.
