Abstract: A memory system and method for power-based operation scheduling are provided. In one embodiment, a memory system begins to perform a plurality of operations in an order in which they are stored in a queue. Before performing a next operation in the queue, the memory system determines whether the power consumed by performing the next operation would exceed a maximum power threshold. In response to determining that the power consumed would exceed the maximum power threshold, the memory system selects an operation out of order from the queue to perform instead, so the maximum power threshold would not be exceeded. Other embodiments are provided.

Abstract: A method and system are disclosed for improved block erase cycle life prediction and block management in a non-volatile memory. The method includes the storage device tracking information relating to a first erase cycle count at which the block erase time exceeded a predetermined threshold relative to a first erase cycle at which this occurred in other blocks. Blocks having a later relative erase cycle at which the erase time threshold is exceeded are assumed to have a greater erase cycle life than those that need to exceed the erase time threshold at an earlier erase cycle. This information is used to adjust wear leveling in the form of free block selection, garbage collection block selection and other block management processes. Alternatively or in combination, the predicted erase cycle life information is used to adjust program and/or erase parameters such as erase voltage and time.

Abstract: A storage module and method for scheduling memory operations for peak-power management and balancing are provided. In one embodiment, a storage module maintains a count of time slots over a period of time. The period of time corresponds to an amount of time between periodic power peaks of a memory operation. For each time slot, the storage module determines whether to commence a memory operation on one or more of the plurality of memory dies based on whether a power peak generated in the time slot by the memory operation would exceed a power threshold allowed for the time slot. Other embodiments are provided.

Abstract: A storage module and method are provided for optimized power utilization. In one embodiment, a storage module is provided comprising a storage controller and a plurality of memory dies in communication with the storage controller. The storage controller determines if sufficient power is available to perform an operation on one of the memory dies. In response to determining that sufficient power is not available to perform the operation on one of the memory dies, the storage controller determines if suspending an in-progress operation on another one of the memory dies would provide enough power to perform the operation. In response to determining that suspending the in-progress operation would provide enough power to perform the operation, the storage controller suspends the in-progress operation and performs the operation. Instead of suspending an in-progress operation, the storage controller can instead use a reduced power version of the operation or the in-progress operation.
