Abstract
A secure data storage device for preventing tampering with data stored thereon includes a two-dimensional memory array for storing data, the array includes a predetermined number of data words. Each data word includes a set of bits, and is associated with a single physical address in the memory array. A key storage area for storing a key of the data storage device is included in the device. The secure data storage device includes an address conversion unit configured to convert a logical address to a corresponding physical address which points to a location in the memory array. The device includes a bit mixing unit for mixing bit values of an input data word to obtain a mixed word value, such that the mixed word value is a rearrangement of the bit values of the input data word. The device is electrically connectable to a host.
