Sughrue Mion, PLLC
Universal flash storage (UFS) device and computing device and computing device including storage UFS device for reporting buffer size based on reuse time after erase
A storage device includes a nonvolatile memory device that includes a plurality of memory blocks, and a controller that uses some memory blocks of the plurality of memory blocks as a buffer area. Memory blocks storing invalid data from among the some memory blocks are invalid memory blocks, and the controller identifies memory blocks, of which an elapsed time after erase is greater than a reuse time, from among the invalid memory blocks as an available buffer size, and provides the available buffer size to an external host device.
