Abstract: A semiconductor system includes a CPU connected to a heterogeneous memory module via a system bus. The heterogeneous memory module includes; a volatile memory module, a nonvolatile memory module, an internal bus separate from the system bus and connecting the volatile memory module and the nonvolatile memory module, and a swap manager configured to control execution of a swap operation transferring target data between the volatile memory module and nonvolatile memory module using the internal bus and without using of the system bus.
