    Abstract: System and methods for proactively refreshing portions of a nonvolatile memory including a memory system that proactively refreshes a portion of nonvolatile memory based on data associated with the portion. The data may include the time elapsed since the portion was last refreshed, the number of times the portion has been cycled, and the average operating temperature of the nonvolatile memory. A portion of nonvolatile memory, when meeting certain criteria determined from the data, may be proactively refreshed during a downtime when the nonvolatile memory is not otherwise being accessed.

    Abstract: Multipage preparation commands for non-volatile memory systems are disclosed. The multipage preparation commands supply data that can be used to prepare a non-volatile memory device for forthcoming multipage program operations. A host controller can use the commands ahead of a multipage program operation to optimize usage of a multipage program command. The non-volatile memory device can use the commands to configure the non-volatile memory in preparation for a subsequent operation, such as changing a command order or using the most optimized command set for the subsequent operation.

    Abstract: In a non-volatile memory system, physically separate power rails are provided from a host system to a NVM device for independently power cycling a controller and memory array in the NVM device. The controller of the NVM device can send a power cycle request signal to the host system over a host channel, or updates a status register in the NVM device. The host system receives and decodes the power cycle request signal, or reads the status register, and performs the power cycle request, which can include power cycling the controller or the memory array in the NVM device, or both. The power cycle request can be based on a power state of the non-volatile memory system, which can be managed by the controller or the host system, or both.
