destructed due to crosstalk and radiation but we can restore their data by using error-correcting codes. However, non-volatile memories consume a large amount of energy in writing. How to reduce writing bits even when using error-correcting codes is one of the challenges in non-volatile memory design. We have proposed a Doughnut code, which is a new bit-write-reducing and error-correcting code. In addition, we have proposed a code expansion method. When we apply our code expansion method to Doughnut code, we can obtain expanded Doughnut codes. Expanded Doughnut codes are error-correcting codes which can reduce the number of writing bits. In this paper, we demonstrate experimental evaluations from the viewpoint of energy reduction of our proposed expanded Doughnut codes. Experimental results show that the write-reducing code reduces energy consumption by up to 32% compared to Hamming code.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムとLSIの設計技術（SLDM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2014-11-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"34","bibliographicVolumeNumber":"2014-SLDM-168"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:50:22.409471+00:00","id":107133,"links":{}}
