SEMICONDUCTOR DEVICE AND SEMICONDUCTOR MODULE

PROBLEM TO BE SOLVED: To provide a semiconductor device and semiconductor module which allow the lamination of a plurality of memory units, can decease the number of selection signal terminals to select any of the memory units laminated in plurality and can make a size smaller and capacity greater. SOLUTION: The semiconductor device 1 has the memory unit 10A, the selection signal terminals 311 and 312 and an identification unit 30A. A memory unit selection signal CS1 common to the plural memory units (10A to 10D) is supplied to the selection signal terminal 311 and a common memory unit selection signal CS2 common to the selection signal terminal 312. The identification unit 30A identifies the memory unit 10A with respect to the other memory units 10B to 10D in accordance with the common memory unit selection signals CS1 and CS2. The semiconductor devices 2 to 4 of the same structure as the structure of the semiconductor device 1 are laminated on the semiconductor device 1, by which the semiconductor module may be built.
