Memory systems and components thereof perform clustering on workload items. Such a memory system comprises a memory device from which data is read and to which data is written; and a memory controller that receives from a host workload items in a workload sequence, each workload item being defined by at least a start logical block address (LBA) and a length. The memory controller merges sequential workload items in the workload sequence to constitute a single workload item; identifies a start workload item for a candidate cluster; stores the LBA and a hit count of the start workload item in a hash table of the memory controller; identifies an end workload item for the candidate cluster; determines whether the candidate cluster is found in the workload sequence more than a threshold number of times; and, if so, accepts the candidate cluster.

Workload clusterization for memory system and method of executing the same

Systems and methods are provided for predicting commands. A controller of a memory system includes a receiver for sequentially receiving a plurality of commands for the memory device in a plurality of windows, and a control component including a finite state machine for training multiple groups of states based on characteristics of the plurality of windows, and predicting a characteristic of next commands, which is to be received in a next window subsequent to a last window among the plurality of windows, based on the multiple groups of states.
