Semiconductor device including semiconductor chips and operating method thereof

Abstract

A semiconductor device and an operating method of the semiconductor device are provided. The semiconductor device includes a plurality of homogeneous semiconductor chips, and an interposer on which the plurality of homogeneous semiconductor chips are disposed. Each of the plurality of homogeneous semiconductor chips manages a memory map including address information. The memory map includes a plurality of system memory regions respectively allocated to the plurality of homogeneous semiconductor chips, and a private memory region shared by the plurality of homogeneous semiconductor chips. The private memory region is mirrored and copied to a mirror region of each of the plurality of system memory regions, and the plurality of homogeneous semiconductor chips perform internal operations by using the private memory region.
