Abstract
A Flash based memory comprising a Flash translation layer which comprises first translation information associating a first logical address of a logical file system emulating a sectored storage medium, the logical address being a logical sector start address with a first physical address of said flash based memory. The logical file system comprises a number of logical stuffing bits expanding a logical size of data of a file stored in said Flash based memory such that the expanded logical size corresponds to an integer number of logical sectors and the Flash translation layer comprises second translation information associating a second logical address with a second physical address and depending on said number of logical stuffing bits, the file being stored in a contiguous physical address sequence starting at the first physical address and ending at the second physical address.
