| 摘要 |
A semiconductor device includes an interface chip and a plurality of DRAM chips consecutively layered on the interface chip. A plurality of source electrodes, a plurality of ground electrodes, and a plurality of signal electrodes penetrate DRAM chips and interconnect the DRAM chips to the interface chip, which is connected to an external circuit. Each source electrode, a corresponding signal electrode and a corresponding ground electrode are arranged adjacent to one another in this order to reduce electromagnetic noise during operation of the DRAM chip.
