Samsung patents memory chip that performs math calculations inside
Samsung describes a memory device that includes a built-in operator to perform specific math tasks called multiply-accumulate operations. This design allows the chip to process data directly within the memory bank rather than moving it to a separate processor.
In the filing’s own words
A memory device includes a memory bank comprising a memory cell array, a memory controller, and an operator, wherein the operator comprises a multiply-accumulate (MAC) array configured to perform outer product and accumulation operations between column vectors of a first size including non-zero (NZ) values of a first input matrix and row vectors of a second size including NZ values of a second input matrix received from the memory cell array, an output buffer configured to store an operation result based on each column vector and row vector of the MAC array, wherein the output buffer has a predetermined tile size corresponding to the first size and the second size, and a vector register file configured to load the operation result from the output buffer and provide the operation result to the MAC array for performing an accumulation operation.
What exactly they claim (claim 1)
1. A memory device comprising: a memory bank comprising: a memory cell array; a memory controller; and an operator, wherein the operator comprises: a multiply-accumulate (MAC) array configured to perform outer product and accumulation operations between column vectors of a first size including non-zero (NZ) values of a first input matrix and row vectors of a second size including NZ values of a second input matrix received from the memory cell array; an output buffer configured to store an operation result based on each column vector and row vector of the MAC array, wherein the output buffer has a predetermined tile size corresponding to the first size and the second size; and a vector register file configured to load the operation result from the output buffer and provide the operation result to the MAC array for performing an accumulation operation.
