    摘要： A method for saving an address map in a memory device is provided. In one embodiment, a logical-to-physical address map is stored in a volatile memory of a memory device. The memory device receives a command from a host device to perform an operation that is associated with a power-down sequence of the host device, such as a flush cache command. In response to receiving the command, the memory device performs the operation and saves the logical-to-physical address map in a non-volatile memory of the memory device. In this way, the command triggers both the performance of the operation and the saving of the logical-to-physical address map in the non-volatile memory of the memory device.

    摘要翻译： 提供了一种用于在存储器件中保存地址映射的方法。 在一个实施例中，逻辑到物理地址映射存储在存储器件的易失性存储器中。 存储装置接收来自主机装置的命令，以执行与主机装置的断电顺序相关联的操作，例如闪存高速缓存命令。 响应于接收到该命令，存储器件执行操作并将逻辑到物理地址映射保存在存储器件的非易失性存储器中。 以这种方式，该命令触发操作的性能和存储器件的非易失性存储器中的逻辑到物理地址映射的保存。
