memory has many advantages such as low leakage power and non-volatility. However, there are problems that a non-volatile memory consumes a large amount of energy in writing and that the maximum number of bit re-writings is limited. We have proposed a Hamming-code based bit-write reduction method using data encoding/decoding but its encoder/decoder becomes too much large. In this paper, we propose small-sized encoder/decoder circuit design for the bit-write reduction codes. In this design, we simplify data encoding/decoding by using code redundancy. Experimental results show the efficiency of our encoder/decoder design.","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":"35","bibliographicVolumeNumber":"2014-SLDM-168"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:50:22.459053+00:00","id":107134,"links":{}}
