  • Publication number: 20220197818
    Abstract: The invention introduces a method for performing operations to namespaces of a flash memory device, by a processing unit of a storage device, at least including the steps: receiving a cross-namespace data-movement command from a host, requesting to move user data of a first logical address of a first namespace to a second logical address of a second namespace; cutting first physical address information corresponding to the first logical address of a first logical-physical mapping table corresponding to the first namespace; and storing the first physical address information in an entry corresponding to a second logical address of a second logical-physical mapping table corresponding to the second namespace.

  • Patent number: 10664414
    Abstract: A controller for a data storage device is disclosed. The controller includes an encryptor and electronic fuses. The electronic fuses is provided for storage of a key which is supposed to be used by the encryptor to encrypt user data before storing the user data in the data storage device. When a user deletes the user data, the controller changes at least one bit of the key stored in the electronic fuses from ‘0’ to ‘1’. Due to the change of the key stored in the electronic fuses for the encryptor, the deleted user data is fully prevented from leaking from the data storage device. A data storage device with a high confidential level is achieved.

  • Patent number: 10649893
    Abstract: Namespace planning of non-volatile memory that takes advantage of multi-channel accessing and considers multi-channel properties is provided. A data storage device includes a non-volatile memory and a controller. The controller accesses the non-volatile memory through multiple channels. When performing namespace planning on the non-volatile memory, the controller makes each assigned channel correspond to just one namespace.

  • Publication number: 20190114112
    Abstract: Namespace planning of a data storage device that takes advantage of multi-channel access and considers multi-channel properties is provided. In cases with only one namespace, the host averagely assigns logical addresses of user data to the different channels to correspond to physical addresses accessed through the channels. In cases with multiple namespaces, the host averagely assigns the channels to the namespaces and thereby each namespace corresponds to the same number of channels. For each namespace, the host assigns logical addresses of user data to the assigned channels to correspond to physical addresses accessed through the assigned channels. To implement the writing of user data, the host outputs an access command that indicates the user data and physical addresses corresponding to the logical addresses of the user data.
