A semiconductor apparatus includes a base substrate and a logic chip disposed on the base substrate. The logic chip includes a memory control circuit, a first through silicon via, and a second through silicon via. The memory control circuit is disposed on a first surface of a substrate of the logic chip, and a memory chip is disposed on a second surface of the substrate of the logic chip. The first through silicon via electrically connects the memory control circuit and the memory chip, the second through silicon via is electrically connected to the memory chip and is configured to transmit power for the memory chip, the second through silicon via is electrically insulated from the logic chip, and the first surface of the substrate of the logic chip faces the base substrate.
