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.","PeriodicalId":325602,"journal":{"name":"2022 IEEE International Conference on Integrated Circuits, Technologies and Applications (ICTA)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125547469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
