  • Patent number: 10203896
    Abstract: A method of operating a universal flash storage (UFS) device communicating with a UFS host via a link is provided. The method determines in the UFS device whether a warm reset of the link is necessary while the UFS device is communicating with the UFS host via the link. Upon determining that the warm reset of the link is necessary, the UFS device initiates the warm reset of the link.

  • Publication number: 20140078344
    Abstract: An image processing system includes a host that generates continuous shooting image data (CSID), and a flash storage device including a memory cell array including a first memory region and a second memory region. A portion of the first memory region is a dedicated CSID buffer region that temporarily stores only CSID. The second memory region stores normal data provided to the flash storage device by the host during a normal program operation. The first memory region supports data access operations including the normal program operation performed at a first speed, and the second memory region supports data access operations performed at a second speed slower than the first speed.

  • Patent number: 8127071
    Abstract: A semiconductor memory device includes adjacent planes and a control module. The adjacent planes include a reserve field and a data field having multiple blocks. The blocks of each of the reserve and data fields are successively arranged over the adjacent planes to form a multi-plane operation group. The control module is configured to control the adjacent planes to conduct a first operation or a second operation in accordance with whether the reserve field includes free blocks corresponding to a unit of the multi-plane operation group. The first operation includes replacing blocks of the data field with free blocks of the reserve field in the unit of the multi-plane operation group. The second operation includes replacing one block of the data field with one free block of the reserve field.
