Non-deterministic window scheduling for data storage systems

Abstract

A semiconductor data storage memory can be arranged with an accumulated list in a memory of background operations to be carried out upon a semiconductor memory formed of one or more non-volatile memory dies. When a deterministic window interval is entered responsive to a request from a host during which data transfers between the host and the semiconductor memory meet a minimum predetermined data transfer rate, the accumulated list is sorted into a first set of the background operations that can be performed during the deterministic window interval while maintaining the minimum predetermined data transfer rate and a remaining second set of the background operations. The first set of the background operations is performed during the deterministic window interval prior to the second set of background operations being performed after a conclusion of the deterministic window interval.
