computation-in-memory using ferroelectric FETs (FeFETs) with high on/off current ratio. To store the weights of the neural networks, multiple FeFETs are connected like AND-type flash array. As pre-neurons information of the neural networks, the input is given to the source-line of the FeFET. Multiply-accumulate (MAC) result is obtained by Phase 1) multiplying inputs and weights by source-follower read to 32 multiply-lines (MLs) in parallel and Phase 2) accumulating capacitance of parallel 1024 accumulate-lines (ALs) by charge-sharing. Unlike the conventional current-sensing CiM, DC current flows in multiply-phase, and no active power is consumed in accumulate-phase in the proposed voltage-sensing FeFET CiM. As a result, the proposed FeFET CiM achieves 66 TOPS/W high throughput and high energy efficiency by parallel MAC operation.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"62","bibliographic_titles":[{"bibliographic_title":"DAシンポジウム2021論文集"}],"bibliographicPageStart":"61","bibliographicIssueDates":{"bibliographicIssueDate":"2021-08-25","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2021"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":212627,"links":{}}
