DATA STORAGE DEVICE AND DATA MANAGEMENT METHOD FOR PROCESSING OF A MAPPING TABLE CAPABLE OF INFORMING PAGE INFORMATION STORED IN THE NEXT DATA THROUGH FORWARD LINKS

摘要

PURPOSE: A data storage device and a data management method for processing of a mapping table are provided to recover the mapping table by informing the page information in which next data is stored through a forward links.;CONSTITUTION: A non-volatile semiconductor memory(1) is partitioned into blocks. The block is partitioned into pages having data area and spare area. A controller(2) stores forward links informing the location of the page in which next data is saved in the spare area of the page. The controller selects the highest forward link which is the most distant from data area among forward links as the most reliable forward link.;COPYRIGHT KIPO 2012
