Computing device having a non-volatile weight memory

Abstract: a computing device comprises: a dynamic random access memory (dram) storing one or more input matrices, each containing numeric inputs; a non-volatile memory device storing one or more weight matrices; a processor comprising a pair of static random access memories (sram), the processor can: load the input matrix from the dram into a first sram of the pair and the weight matrix from the non-volatile memory device into a second sram of the pair, execute matrix operations on the loaded input matrix and the weight matrix; and transfer a corresponding output matrix from the matrix operations to the dram, wherein a first sram is connected to the dram via a data bus and a second sram is connected to the non-volatile memory device via one or more direct channels independent from the data bus, allowing a direct transfer of the weight parameters from the non-volatile memory to the first sram.
