Zusammenfassung:The invention relates to a high-efficiency data storage device and a control method of a non-volatile memory. The memory controller dynamically maintains mapping information on a temporary memory anddisplays physical space information mapped by a logic address identified by a host. And the memory controller marks a physical space of a nonvolatile memory or marks an address in a data cache space by using the first bit to the Nth bit of the physical space information. The memory controller does not plan a specific bit in the physical space information to distinguish whether the physical space information points to the non-volatile memory or the data cache space. And the memory controller is used for distinguishing whether the entity space information points to the nonvolatile memory or thedata cache space according to meaningless values of the entity space of the nonvolatile memory in the values formed by the first bit to the Nth bit. 本发明涉及高效能的数据储存装置以及非挥发式存储器的控制方法。存储器控制器在一暂存存储器上动态维护映射资讯,显示一主机辨识的逻辑地址映射的实体空间资讯。该存
