    • A method for protecting information in a device includes providing a device with a non-secure hardware domain, a processor having a software-controlled mode of operation, and a secure hardware domain having a secure memory that is inaccessible by the processor when the processor is operating in the software-controlled mode of operation. Data from the non-secure hardware domain is established in the secure hardware domain. Computing operations are executed on the data in the secure hardware domain to produce a result. The secure hardware domain is purged, while retaining the result therein. The result is thereafter returned from the secure hardware domain into the non-secure hardware domain.

    • A first storage device provides a host device with access to a private memory area by communicating a password between the first storage device and a second storage device via the host device using a double-encryption scheme. In one embodiment, a host device receives a twice-encrypted password from a first storage device, sends the twice-encrypted password to a second storage device, receives a once-encrypted password from the second storage device, decrypts the once-encrypted password to obtain the password, and sends the password to the first storage device. In another embodiment, a first storage device sends a twice-encrypted password to a host device, receives the password from the host device after the twice-encrypted password is decrypted by a second storage device and the host device, and provides the host device with access to the private memory area only if the password matches one that is stored in the first storage device.
    • 第一存储设备通过使用双加密方案经由主机设备在第一存储设备和第二存储设备之间传送密码来向主机设备提供对专用存储器区域的访问。 在一个实施例中,主机设备从第一存储设备接收两次加密的密码,将二次加密的密码发送到第二存储设备,从第二存储设备接收一次加密的密码,将一次加密的密码解密为 获取密码,并将密码发送到第一个存储设备。 在另一个实施例中,第一存储设备向主机设备发送两次加密的密码,在由第二存储设备和主设备解密两次加密的密码之后从主机设备接收密码,并向主机设备提供 仅当密码与存储在第一存储设备中的密码匹配时,才能访问私有内存区域。

    • A method and memory device for implementing long operations and supporting multiple streams are provided. In one embodiment, a memory device receives data and a command from a host to perform an operation on the data, wherein a time required for the memory device to complete the operation exceeds a maximum response time for the memory device to respond to the command. The memory device begins performing the operation on the data and, before exceeding the maximum response time and before completing the operation, sends the context of the operation to the host. At a later time, the memory device receives from the host: (i) a command to resume performing the operation and (ii) the context. The memory device then resumes performing the operation on the data based on the context received from the host.
    • 提供了一种用于实现长操作并支持多个流的方法和存储器件。 在一个实施例中,存储器设备从主机接收数据和命令以执行对数据的操作,其中存储器设备完成操作所需的时间超过存储器设备响应命令的最大响应时间。 存储设备开始对数据执行操作,并且在超过最大响应时间之前并且在完成操作之前,将操作的上下文发送到主机。 在稍后的时间,存储器装置从主机接收:(i)恢复执行操作的命令和(ii)上下文。 然后,存储器设备基于从主机接收的上下文恢复对数据的操作。

    • A storage device and method for updating a shadow master boot record (MBR) are provided. In one embodiment, a storage device is provided having a memory with a first storage area and a second storage area. The storage device receives updated sectors of the shadow MBR from a host device and writes the updated sectors in the second storage area. The storage device determines a highest written sector in the first storage area that is occupied by the shadow MBR. The storage device copies the non-updated sectors of the shadow MBR from the first storage area to the second storage area, wherein only the non-updated sectors up to the highest written sector are copied. Accordingly, any non-updated sectors above the highest written sector are not copied from the first storage area to the second storage area. The storage device then designates the second storage area as storing a current version of the shadow MBR.
    • 提供了一种用于更新影子主引导记录(MBR)的存储设备和方法。 在一个实施例中,提供具有具有第一存储区域和第二存储区域的存储器的存储设备。 存储设备从主机设备接收影子MBR的更新扇区,并将更新的扇区写入第二存储区域。 存储装置确定由影子MBR占据的第一存储区域中的最高写入扇区。 存储装置将影子MBR的未更新扇区从第一存储区域复制到第二存储区域,其中仅复制直到最高写入扇区的未更新扇区。 因此,高于最高写入扇区的任何非更新扇区不会从第一存储区复制到第二存储区。 然后,存储装置将第二存储区域指定为存储影子MBR的当前版本。
