Patent ID: 10083891

Abstract:
An IC chip package includes: a base substrate; an interposer substrate including a plurality of wires therein, the interposer substrate operatively coupled to the base substrate; and a processor operatively positioned on the interposer substrate. A memory is operatively positioned on the interposer substrate and operatively coupled to the processor through the interposer substrate. The memory includes: a 3D DRAM stack, a thermoelectric heat pump coupled directly to an uppermost layer of the 3D DRAM stack, and a memory controller operatively coupled to the 3D DRAM stack to control operation of the 3D DRAM stack. A temperature controller operatively coupled to the thermoelectric heat pump controls a temperature of the 3D DRAM stack using the thermoelectric heat pump. A lid may thermally couple to an uppermost surface of the processor and an uppermost surface of the thermoelectric heat pump.
