摘要：
A data storage device includes a secure data storage portion including a log memory. The log memory is formed of a plurality of banks, and stores history information in the plurality of banks in a ring-like fashion. The plurality of banks are designated by addresses (0-(N−1)), respectively. Each of the items of the history information respectively stored in the banks includes a management number region, a license ID (LID) region, a Ks2x region, an ST1 region, an ST2 region, a KPcmy region and a LBA region.
