Abstract
High performance data storage device is disclosed, which has a memory controller dynamically updating mapping information on the temporary storage to manage physical space information mapped to a logical address recognized by a host. The memory controller uses a first bit to an Nbit of the physical space information to indicate a physical space of the non-volatile memory or a cache address of the data cache space, without using additional bits to map the physical space information to the non-volatile memory or the data cache space, where N is a number greater than one. Among numbers formed by the first to the Nbit, the memory controller uses numbers corresponding to non-existent physical space of the non-volatile memory to map the physical space information to the non-volatile memory or the data cache space.
