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.

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 handling errors during device bootup from a non-volatile memory ("NVM"). A NVM interface of an electronic device can be configured to detect errors and maintain an error log in volatile memory while the device is being booted up. Once device bootup has completed, a NVM driver of the electronic device can be configured to correct the detected errors using the error log. For example, the electronic device can move data to more reliable blocks and/or retire blocks that are close to failure, thereby improving overall device reliability.

摘要： Systems and methods are disclosed for dynamically allocating power for a system having non- volatile memory. A power budgeting manager of a system can determine if the total amount of power available for the system is below a pre-determined power level (e.g., a low power state). While the system is operating in the low power state, the power budgeting manager can dynamically allocate power among various components of the system (e.g., a processor and non¬ volatile memory).

摘要： Systems and methods are provided for handling temporary data that is stored in a non-volatile memory, such as NAND flash memory. The temporary data may include hibernation data or any other data needed for only one boot cycle of an electronic device. When storing the temporary data in one or more pages of the non-volatile memory, the electronic device can store a temporary marker as part of the metadata in at least one of the pages. This way, on the next bootup of the electronic device, the electronic device can use the temporary marker to determine that the associated page contains unneeded data. The electronic device can therefore invalidate the page and omit the page from its metadata tables.
摘要翻译：提供了用于处理存储在诸如NAND闪存之类的非易失性存储器中的临时数据的系统和方法。临时数据可以包括休眠数据或电子设备的仅一个引导周期所需的任何其他数据。当将该临时数据存储在非易失性存储器的一个或多个页面中时，电子设备可以将临时标记作为元数据的一部分存储在至少一个页面中。这样，在电子设备的下次启动时，电子设备可以使用临时标记来确定相关联的页面包含不需要的数据。因此，电子设备可以使页面无效，并从其元数据表中省略页面。

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。
