Abstract: A method and system are disclosed that permit a storage device to remain fully functional despite running out of a sufficient supply of spare blocks in memory. The storage device includes a non-volatile memory and a controller, where the controller is configured to detect an insufficiency of spare blocks and convert operative blocks to spare blocks. The method includes techniques for selecting certain operative blocks for conversion to spare blocks using the storage manager on the storage device and a file system manager that may or may not be part of the storage device.

Abstract: Methods for writing data from a source location to a destination location in a memory device are provided. In one embodiment, a memory device receives a command from a host device, wherein the command specifies a logical address of a source location in the memory and a logical address of a destination location in the memory. The memory device translates the logical addresses of the source and destination locations to physical addresses of the memory, reads data from the source location, and writes the data to the destination location. In this embodiment, the data is read from the source location and written to the destination location without a need of further involvement of the host device after the host device sends the command to the memory device. Other embodiments are provided.

Abstract: The embodiments described herein provide methods for executing a command to write data from a source location to a destination location in a memory device. In one embodiment, a memory device receives, from a host device, a command to write data from a source location to a destination location in the memory device. The memory device executes the command by changing the memory device's logical-to-physical address map without reading the data from the source location and writing the data to the destination location and without a need of further involvement of the host device after the host device sends the command to the memory device.
