Abstract: A circuit includes a memory array with memory cells arranged in a matrix of rows and columns, where each row includes a word line connected to the memory cells of the row, and each column includes a bit line connected to the memory cells of the column. Computational weights for an in-memory compute operation (IMCO) are stored in the memory cells. A word line control circuit simultaneously actuates word lines in response to input signals providing coefficient data for the IMCO by applying word line signal pulses. A column processing circuit connected to the bit lines processes analog signals developed on the bit lines in response to the simultaneous actuation of the word lines to generate multiply and accumulate output signals for the IMCO. Pulse widths of the signal pulses are modulated to compensate for cell drift. The IMCO further handles positive/negative calculation for the coefficient data and computational weights.

Abstract: An aggregated communication network includes one or more communication networks and a plurality of network nodes arranged in a plurality of hierarchical layers, the network nodes including a central node at a highest layer and a remaining network nodes being arranged, as part of the one or more communication networks, in layers below the highest layer, with one or more spatially distributed network nodes at each layer below the highest layer. The network nodes in each communication network are interconnected in a tree-like structure via communication links, with respective sub-branches extending from the network nodes via network nodes in lower layers. The one or more communication networks are connected to the central node in a star-like structure via respective communication links between the central node and respective network nodes in a next-to-highest layer. The communication links between network nodes in a lowest layer.
