In-memory matrix multiplication and its use in neural networks

摘要

A method for an associative memory array of the present invention comprises the steps of storing each column of a matrix in an associated column of the associated memory array, storing each bit in the row j of the matrix in an R-matrix-row-j row of the array -; Storing a vector in each of the associated columns, wherein bit j from the vector is stored in an R-vector-bit-j that is the row of the array. The method also includes concurrently activating R-vector-bit-j and R-matrix-row-j rows of the vector-matrix pair to simultaneously receive the result of the Boolean function on all associated columns, Using the result on the associated column to calculate the product between the pairs of rows, and writing the product to R-product-j that is low in the array.
