1. A chip system, comprising:
a first chip, comprising a first dynamic random access memory (DRAM) controller and a first serial transmission interface;
a first DRAM, coupled to the first DRAM controller of the first chip;
a second chip, comprising a second DRAM controller and a second serial transmission interface, wherein the second serial transmission interface is coupled to the first serial transmission interface; and
a second DRAM, coupled to the second DRAM controller of the second chip;
wherein when the first chip intends to store first data and second data, the first chip stores the first data into the first DRAM via the first DRAM controller, and transmits the second data to the second chip via the first serial transmission interface; and the second chip stores the second data into the second DRAM via the second DRAM controller.
