    Abstract: Systems and methods for managing data in non-volatile memory devices across a large range of operating temperatures are provided. Embodiments discussed herein selectively reprogram previously programmed data at a temperature that better enables the data to be read regardless of where within the range of operating temperatures the data is being read. Circuitry and methods discussed herein can keep track of a program temperature associated with each portion of non-volatile memory and use this information along with other criteria to selectively perform temperature based moves of data. This enables a mechanism for data to programmed in out-of-bounds temperature ranges to be reprogrammed within an in-bounds temperatures range so that a temperature delta between the reprogrammed temperature and the read operation temperature is below a threshold that ensure efficient and error free read operations to be performed.

    Abstract: 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).

    Abstract: Systems and methods are disclosed for monitoring the time it takes to perform a write operation, and based on the time it takes, a determination is made whether to retire a block that is a recipient of the write operation. The time duration of the write operation for a page or a combination of pages may indicate whether any block or blocks containing the page or combination of pages is experiencing a physical failure. That is, if the time duration of the write operation for a particular page exceeds time threshold, this may indicate that this page requires a larger number of program cycles than other pages. The longer programming cycle can be an indication of cell leakage or a failing block.

    Abstract: Systems and methods for writing to high-capacity memory are disclosed. In high-capacity memory systems in which the capacity of the characteristic portion of the memory (e.g., a page of NAND flash memory) exceeds the capacity of a buffer used to write to the memory, underutilization issues are prevalent. Data organized in the buffer can be combined with additional data to improve utilization of the characteristic portion. According to various embodiments, the additional data can include duplicate copies of the data, whitened data, or any other suitable type of data.

    Abstract: Systems and methods are disclosed for limiting power consumption of a non-volatile memory (NVM) using a power limiting scheme that distributes a number of concurrent NVM operations over time. This provides a “current consumption cap” that fixes an upper limit of current consumption for the NVM, thereby eliminating peak power events. In one embodiment, power consumption of a NVM can be limited by receiving data suitable for use as a factor in adjusting a current threshold from at least one of a plurality of system sources. The current threshold can be less than a peak current capable of being consumed by the NVM and can be adjusted based on the received data. A power limiting scheme can be used that limits the number of concurrent NVM operations performed so that a cumulative current consumption of the NVM does not exceed the adjusted current threshold.

    Abstract translation: 公开了用于使用分配多个并发NVM操作随时间推移的功率限制方案来限制非易失性存储器（NVM）的功率消耗的系统和方法。 这提供了一个“电流消耗上限”，用于确定NVM的电流消耗上限，从而消除峰值功率事件。 在一个实施例中，可以通过接收适合用作从多个系统源中的至少一个调整当前阈值的因素的数据来限制NVM的功耗。 当前阈值可以小于能够被NVM消耗的峰值电流，并且可以基于所接收的数据进行调整。 可以使用功率限制方案，其限制执行的并行NVM操作的数量，使得NVM的累积电流消耗不超过调整的电流阈值。
