摘要： Systems and methods are disclosed for secure relocation of encrypted files for a system having non-volatile memory (“NVM”). A system can include an encryption module that is configured to use a temporary encryption seed (e.g., a randomly generated key and a corresponding initialization vector) to decrypt and encrypt data files in an NVM. These data files may have originally been encrypted with different encryption seeds. Using such an approach, data files can be securely relocated even if the system does not have access to the original encryption seeds. In addition, the temporary encryption seed allows the system to bypass a default key scheme.

摘要： Systems and methods are disclosed for managing a non-volatile memory (“NVM”), such as a flash memory. To prevent data errors due to leakage effects, the NVM may be refreshed. For example, a reserved portion of the NVM may be selected, and a predetermined pattern can be stored into the reserved portion. The reserved portion can then be monitored for storage deterioration over time. After determining that storage deterioration of the reserved portion has occurred, the NVM can be refreshed. In some embodiments, a controller can attempt to distinguish data errors due to leakage effects from data errors due to disturb issues.
摘要翻译：公开了用于管理诸如闪存之类的非易失性存储器（“NVM”）的系统和方法。为了防止由于泄漏影响引起的数据错误，NVM可能会刷新。例如，可以选择NVM的保留部分，并且可以将预定模式存储到保留部分中。然后可以监视保留部分以随时间的存储恶化。在确定保留部分的存储恶化已经发生之后，可以刷新NVM。在一些实施例中，控制器可以尝试将由于泄漏影响引起的数据错误与由于干扰问题引起的数据错误区分开。

摘要： Systems and methods are disclosed for configuring a non-volatile memory (“NVM”). In some embodiments, each block of the NVM can include a block table-of-contents (“TOC”), which can be encoded (e.g., run-length encoded) and dynamically-sized. Thus, as user data is being programmed to a block, the size of a block TOC can be concurrently recalculated and increased only if necessary. In some embodiments, the NVM interface can use a weave sequence stored in the context information and at least one weave sequence associated with each page of a block to determine whether to replay across the pages of the block after system boot-up.

摘要： Systems and methods are disclosed for trim token journaling. A device can monitor the order in which trim commands and write commands are applied to an indirection system stored in a volatile memory of the device. In some embodiments, the device can directly write to a page of an NVM with a trim token that indicates that a LBA range stored in the page has been trimmed. In other embodiments, a device can add pending trim commands to a trim buffer stored in the volatile memory. Then, when the trim buffer reaches a pre-determined threshold or a particular trigger is detected, trim tokens associated with all of the trim commands stored in the trim buffer can be written to the NVM. Using these approaches, the same sequence of events that was applied to the indirection system during run-time can be applied during device boot-up.
