Abstract
The invention provides a method for data recovery. In one embodiment, a memory comprises a plurality of pages for data storage. First, first data is obtained from a host. A first page for storing the first data is then selected from the pages of the memory. A start page link indicating the first page is then stored in the memory. The first data, a first page link indicating a next page, and first FTL fragment data corresponding to the first page are then written into the first page. Next data is then obtained from the host. The next data, a next page link indicating a subsequent page, and FTL fragment data corresponding to the next page are written into the next page.
