摘要： Systems and methods are disclosed for partitioning data for storage in a non-volatile memory (“NVM”), such as flash memory. In some embodiments, a priority may be assigned to data being stored, and the data may be logically partitioned based on the priority. For example, a file system may identify a logical address within a first predetermined range for higher priority data and within a second predetermined range for lower priority data, such using a union file system. Using the logical address, a NVM driver can determine the priority of data being stored and can process (e.g., encode) the data based on the priority. The NVM driver can store an identifier in the NVM along with the data, and the identifier can indicate the processing techniques used on the associated data.
摘要翻译：公开了用于分割用于存储在诸如闪存的非易失性存储器（NVM）中的数据的系统和方法。在一些实施例中，可以将优先级分配给正在存储的数据，并且可以基于优先级逻辑地划分数据。例如，文件系统可以识别用于较高优先级数据的第一预定范围内的逻辑地址，并且在较低优先权数据的第二预定范围内识别逻辑地址，诸如使用联合文件系统。使用逻辑地址，NVM驱动器可以确定正在存储的数据的优先级，并且可以基于优先级处理（例如，编码）数据。 NVM驱动程序可以将数据与NVM一起存储在标识符中，并且标识符可以指示在相关数据上使用的处理技术。

摘要： Systems and methods are provided for unmapping unused logical addresses at mount-time of a file system. An electronic device, which includes a non-volatile memory (“NVM”), may implement a file system that, at mount-time of the NVM, identifies all of the logical addresses associated with the NVM that are unallocated. The file system may then pass this information on to a NVM manager, such as in one or more unmap requests. This can ensure that the NVM manager does not maintain data associated with a logical address that is no longer needed by the file system.
摘要翻译：提供了系统和方法，用于在文件系统的安装时解除未使用的逻辑地址。包括非易失性存储器（NVM）的电子设备可以实现在NVM的安装时识别与未分配的与NVM相关联的所有逻辑地址的文件系统。文件系统然后可以将该信息传递到NVM管理器，诸如在一个或多个unmap请求中。这可以确保NVM管理器不维护与文件系统不再需要的逻辑地址相关联的数据。

摘要： Systems, apparatuses, and methods are provided for detecting corrupted data for a system having non-volatile memory, such as NAND Flash memory. In some embodiments, a non-volatile memory (“NVM”) package is provided, which can include a NVM controller and one or more NVM dies. Each NVM die can include one or more blocks, where each block can further include an array of memory cells. One or more of these memory cells can be configured as “multi-level cells” (“MLCs”). In some embodiments, in order to avoid transmitting data obtained from an improperly programmed page of a MLC, a NVM controller can be configured to detect if data obtained from the page is in fact data stored in a different page.

摘要： Systems and methods are disclosed for managing the peak power consumption of a system, such as a non-volatile memory system (e.g., flash memory system). The system can include multiple subsystems and a controller for controlling the subsystems. Each subsystem may have a current profile that is peaky. Thus, the controller may control the peak power of the system by, for example, limiting the number of subsystems that can perform power-intensive operations at the same time or by aiding a subsystem in determining the peak power that the subsystem may consume at any given time.

摘要： Systems and methods are provided for performing incremental garbage collection for non-volatile memories (“NVMs”), such as flash memory. In some embodiments, an electronic device including the NVM may perform incremental garbage collection to free up and erase a programmed block of the NVM. The programmed block may include valid data and invalid data, and the electronic device may be configured to copy the valid data from the programmed block to an erased block in portions. In between programming each portion of the valid data to the erased block, the electronic device can program host data to the erased block. This way, the electronic device can stagger the garbage collection operations and prevent a user from having to experience one long garbage collection operation.

摘要： Systems and methods are provided for storing data to or reading data from a non-volatile memory (“NVM”), such as flash memory, using a metadata redundancy scheme. In some embodiments, an electronic device, which includes an NVM, may also include a memory interface for controlling access to the NVM. The memory interface may receive requests to write user data to the NVM. The user data from each request may be associated with metadata, such as a logical address, flags, or other data. In response to a write request, the NVM interface may store the user data and its associated metadata in a first memory location (e.g., page), and may store a redundant copy of the metadata in a second memory location. This way, even if the first memory location becomes inaccessible, the memory interface can still recover the metadata from the backup copy stored in the second memory location.
