  • Command executing method, memory controller and memory storage apparatus
    Patent number: 9946661
    Abstract: A command executing method for a memory storage apparatus is provided. The method includes grouping logical addresses into logical address groups and assigning a key for each of the logical address groups independently. The method also includes receiving a write command and write data corresponding to the write command and temporarily storing the write data into a buffer memory. The method further includes executing the write command, enabling a direct memory access once to transfer the write data from the buffer memory to a writable non-volatile memory module of the memory apparatus and encrypting each sector data of the write data with keys corresponding to the logical address groups that the logical address storing the sector data belong to.
