Zusammenfassung:A compute-memory circuit included in a computer system includes multiple data storage cells and multiplier circuits. The data storage cells store weight values associated with a first operand. The multiplier circuits are coupled to a global bit line and receive the weight values via local bit lines coupled to the data storage cells. Using the received weight values and activation signals indicative of a second operand, the multiplier circuits modify a voltage level of the global bit line. The resultant voltage level on the global bit line is indicative of a product of the first and second operands, and can be converted to a digital value using an analog-to-digital converter circuit.
