摘要： A method of operation in a non-volatile memory system for deferring, in accordance with a determination to reduce power consumption by the non-volatile memory system, execution of commands in a command queue corresponding to a distinct set of non-volatile memory devices during a respective wait period. In some implementations, the respective wait period for a first distinct set of non-volatile memory devices in at least two distinct sets is at least partially non-overlapping with the respective wait period for a second distinct set of non-volatile memory devices in the at least two distinct sets.

摘要： A method of operation in a non-volatile memory device, including executing a memory operation with respect to a portion of a non-volatile memory device, and measuring a current corresponding to current drawn by at least the portion of the non-volatile memory device during the memory operation. An age metric is determined for at least the portion of the non-volatile memory device based on age criteria including a characteristic of the measured current. In accordance with a determination that the age metric satisfies one or more predefined threshold criteria, one or more configuration parameters associated with the non-volatile memory device are adjusted. After the adjusting, data is read from and data to the portion of the non-volatile memory device according to the one or more adjusted configuration parameters.

摘要： A method of operation in a non-volatile memory system includes starting execution of a first memory operation from a first queue and in conjunction with starting a first timer, set to expire after a first predetermined time interval. The method further includes, in accordance with a determination that the first timer has expired, determining whether a second queue contains at least one memory operation for execution, and if so, suspending the first memory operation, executing a second memory operation from the second queue, and after completing execution of the second memory operation from the second queue, performing one or more subsequent operations (e.g., resuming execution of the first memory operation and restarting the first timer). In addition, the method includes, when the second queue does not contain at least one memory operation for execution, restarting the first timer, and continuing execution of the first memory operation from the first queue.

摘要： Systems and methods disclosed herein are used to efficiently manage low read data. In one aspect, a method includes, in response to detecting occurrence of a first event (e.g., PFail), writing low read data to non-volatile memory of a storage device with a fast SLC programming mode, distinct from a default SLC programming mode. Writing the low read data with the fast SLC programming mode: (i) includes using one or more memory programming parameters distinct from a default set of memory programming parameters used for writing data with the default SLC programming mode and (ii) takes less time per predefined unit of data than writing data with the default SLC programming mode. The method also includes: in response to detecting occurrence of a second event (e.g., host write command), writing data corresponding to the second event with the default SLC programming mode using the default set of memory programming parameters.
