Abstract
A non-volatile memory (NVM) system receives host requests that each specify a memory operation to be performed by the NVM system, the specified memory operations including read operations and write operations, and performs a set of operations for each memory operation specified by a received host request. The set of operations performed for each such memory operation include: initiating performance the memory operation; determining a throttle interval for the memory operation in accordance with at least a first factor, corresponding to available space in a write cache of the non-volatile memory system, and a second factor, corresponding to a metric corresponding to prevalence of write operations in the memory operations specified by the received host requests; and returning to the host system a response associated with the memory operation at a time no earlier than a start time associated with the memory operation plus the determined throttle interval.
