A compute memory system can include a memory array and a controller that generates N-ary weighted (e.g., binary weighted) access pulses for a set of word lines during a single read operation. This multi-row read generates a charge on a bit line representing a word stored in a column of the memory array. The compute memory system further includes an embedded analog signal processor stage through which voltages from bit lines can be processed in the analog domain. Data is written into the memory array in a manner that stores words in columns instead of the traditional row configuration.
