Abstract: Disclosed herein are neural computing dies with stacked neural core regions as well as related methods and assemblies. In some embodiments, a neural computing die may include: a first neural core region; a second neural core region; and an inter-core interconnect region in a volume between the first neural core region and the second neural core region, wherein the inter-core interconnect region includes a conductive pathway between the first neural core region and the second neural core region, and the conductive pathway includes a conductive via.

Abstract: Described herein are stacked memory devices that include some peripheral devices for controlling the memory in a separate layer from one or more memory arrays. The layers of the memory device are connected together using vias, which transfer power and data between the layers. In some examples, a portion of the peripheral devices are included in a memory layer, and another portion are included in a peripheral device layer. Multiple layers of memory arrays and/or peripheral devices may be included, e.g., one peripheral device layer may control multiple layers of memory arrays, or different layers of memory arrays may have dedicated peripheral device layers. Different types of memory arrays, such as DRAM or SRAM, may be included.

Abstract: An analog multiplication circuit includes switched capacitors to multiply digital operands in an analog representation and output a digital result with an analog-to-digital convertor. The capacitors are arranged with a capacitance according to the respective value of the digital bit inputs. To perform the multiplication, the capacitors are selectively charged according to the first operand of the multiplication. The capacitors are then connected to a common interconnect for charge sharing across the capacitors, averaging the charge according to the charge determined by the first operand. The capacitor are then maintained or discharged according to a second operand, such that the remaining charge represents a number of “copies” of the averaged charge. The capacitors are then averaged and output for conversion by an analog-to-digital convertor. This circuit may be repeated to construct a multiply-and-accumulate circuit by combining charges from several such multiplication circuits.
