Abstract: A non-volatile memory device includes an array of non-volatile memory cells that are configured to store weights of a neural network. Associated with the array is a data latch structure that includes a page buffer, which can store weights for a layer of the neural network that is read out of the array, and a transfer buffer, that can store inputs for the neural network. The memory device can perform multiply and accumulate operations between inputs and weight of the neural network within the latch structure, avoiding the need to transfer data out of the array and associated latch structure for portions of an inference operation. By using binary weights and inputs, multiplication can be performed by bit-wise XNOR operations. The results can then be summed and activation applied, all within the latch structure.

Abstract: A non-volatile memory structure capable of storing layers of a deep neural network (DNN) and perform an inferencing operation within the structure is presented. A stack of bonded die pairs is connected by through silicon vias. Each bonded die pair includes a memory die, having one or more memory arrays onto which layers of the neural network are mapped, and a peripheral circuitry die, including the control circuits for performing the convolution or multiplication for the bonded die pair. The multiplications can either be done in-array on the memory die or in-logic on the peripheral circuitry die. The arrays can be formed into columns along the vias, allowing an inferencing operation to be performed by propagating an input up and down the columns, with the output of one level being the input of the subsequent layer.

Abstract: A computer-implemented method for assessing material microstructure of a machine component involves obtaining a raw image of a section of the component captured via a microscope. The method further includes pre-processing the raw image to generate a ternary image defined by pixel data including three levels of intensities.

The method further includes determining a volume associated with the phase based on the identified phase boundaries. The proposed method may be utilized, for example, as an automated tool for assessing material degradation and for quality control of gas turbine engine components.
