Patent number: 11392436Abstract: Aspects of a storage device including a memory and a controller are provided which allow for data associated with a deleted file to be recovered from the memory when the data is overwritten by a new file at the same logical address. To locate the data, the controller may identify a logical address associated with the data based on a directory entry associated with a FAT. The controller may determine a physical location of the data associated with the logical address based on one or more control entries in a L2P mapping table, such as a previous control entry in the table. The controller may also determine the physical location based on a hot count associated with the previous control entry. After the physical location is determined, the controller may associate a new logical address with the physical location of the data to recover the deleted file.Type: GrantFiled: April 1, 2020Date of Patent: July 19, 2022Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.Inventors: Ankit Gupta, Narendhiran Chinnaanangur Ravimohan, Abhinand Amarnath

Patent number: 11385961Abstract: Methods, systems, and devices for adaptive parity techniques for a memory device are described. An apparatus, such as a memory device, may use one or more error correction code (ECC) schemes, an error cache, or both to support access operations. The memory device may receive a command from a host device to read or write data. If the error cache includes an entry for the data, the memory device may read or write the data using a first ECC scheme. If the error cache does not include an entry for the data, the memory device may read or write the data without using an ECC scheme or using a second ECC scheme different than the first ECC scheme.Type: GrantFiled: August 14, 2020Date of Patent: July 12, 2022Assignee: Micron Technology, Inc.Inventors: Justin Eno, William A.

Patent number: 11288150Abstract: A Recovery Maturity Index 1 (RMM) is used to determine whether a particular Information Technology (IT) production environment is relatively mature enough to successfully execute the disaster recovery (DR). The RMI provides a quantitative analysis in terms of a set of categories for elements that characterize the environment and multiple elements for each category. At least some of the elements depend upon the extent to which automation components have been leveraged for disaster recovery. A summation of the scoring elements, which may be a weighted summation, results in an overall quantitative metric. The metric can used to determine whether or not disaster recovery can be expected to be successful.Type: GrantFiled: May 6, 2020Date of Patent: March 29, 2022Assignee: Sungard Availability Services, LPInventor: Darpan Thaker
