Most existing flash translation layer (FTL) schemes are, however, ill-suited for such systems because they were optimized for storage write patterns of embedded systems only. In this paper, we propose a new flash management technique called LAST which is optimized for access characteristics of general-purpose computing systems. By exploiting the locality of storage access patterns, LAST reduces the garbage collection overhead significantly, thus increasing the I\/O performance of flash-based storage devices. Our experimental results show that the proposed technique reduces the garbage collection overhead by 54% over the existing flash memory management techniques.<\/jats:p>","DOI":"10.1145\/1453775.1453783","type":"journal-article","created":{"date-parts":[[2008,10,22]],"date-time":"2008-10-22T12:25:40Z","timestamp":1224678340000},"page":"36-42","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":194,"title":["LAST"],"prefix":"10.1145","volume":"42","author":[{"given":"Sungjin","family":"Lee","sequence":"first","affiliation":[{"name":"Seoul National University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dongkun","family":"Shin","sequence":"additional","affiliation":[{"name":"Sungkyunkwan University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young-Jin","family":"Kim","sequence":"additional","affiliation":[{"name":"Sun Moon University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jihong","family":"Kim","sequence":"additional","affiliation":[{"name":"Seoul National University"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2008,10]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1247480.1247522"},{"key":"e_1_2_1_2_1","unstructured":"E.
