In memory matrix multiplication and its usage in neural networks

Abstract:

A method for an associative memory array includes storing each column of a matrix in an associated column of the associative memory array, where each bit in row j of the matrix is stored in row R-matrix-row-j of the array, storing a vector in each associated column, where a bit j from the vector is stored in an R-vector-bit-j row of the array. The method includes simultaneously activating a vector-matrix pair of rows R-vector-bit-j and R-matrix-row-j to concurrently receive a result of a Boolean function on all associated columns, using the results to calculate a product between the vector-matrix pair of rows, and writing the product to an R-product-j row in the array.
