摘要：Adders and multipliers based on memristive Material Implication (IMPLY) logic are widely used in primary building blocks of Arithmetic Logic Unit (ALU). To solve the issue that the existing IMPLY-based multipliers cannot protect the input operands, this paper presents a novel data non-destructive memristive IMPLY-based semi-parallel multiplier for Computing-in-Memory (CIM) systems, by assigning function-specific memristors for data-protection and introducing additional switches for higher parallelism. Simulation results show that the proposed multiplier can achieve 30% faster than conventional semi-parallel design and 9.1% less memristors against the state-of-art semi-serial design for 4-bit multiplication, while preventing the input weight from destruction as required by CNN weight reuse.
