Claim 16:
17. A method to improve in-memory multiply and accumulate operations, the method comprising:
receiving, with a first multiplexer in a subarray of memory, first values representative of a column of a lookup table (LUT) including entries to represent products of four-bit numbers;
returning, with the first multiplexer, second values from an intersection of a row and the column of the LUT based on a first element of a first operand;
shifting, with shift and adder logic in the subarray, the second values based on at least one of the first element of the first operand or a first element of a second operand; and
storing, in accumulation storage in the subarray, at least the shifted second values.
