Abstract: The multiplication method disclosed herein benefits from the complementary advantages of both Stochastic Computing (SC) and memristive In-Memory Computation (IMC) to enable energy-efficient and low-latency multiplication of data. In summary, the following method are disclosed. (a) Performing deterministic and accurate bit-stream-based multiplication in memory. To this end, the invention disclosed herein uses memristive crossbar memory arrays and Memory-Aided Logic (MAGIC). (b) Using an efficient in-memory method for generating deterministic bit-streams from binary data, which takes advantage of inherent properties of memristive memories. (c) Improving the speed and reducing the memory usage as compared to the State-of-the-Art (SoA) limited-precision in-memory binary multipliers. (d) Reducing latency and energy consumption compared to the SoA accurate off-memory SC multiplication techniques.
