Stacked random-access memory devices with refrigeration

Abstract

Described herein are memory devices that include a cooling structure for cooling one or more memory arrays. The memory arrays may be static random access memory (SRAM) arrays formed in multiple layers as a stacked memory device. The cooling structure may cool one or more layers of an SRAM device. For example, a cooling structure may be formed around the SRAM device and coupled to a cooling device. Alternatively, a cooling layer may be included in a memory device and coupled to one or more thermal interface layers in thermal contact with a memory layer by cold vias. The cold vias transfer a cold temperature from the cooling layer to the thermal interface layer to cool the thermal interface layer and, in turn, the memory arrays.
