US 12,008,249 B2 · Memory system and method of performing background operation

Abstract

A memory controller, a memory system and a method of operating a memory controller controlling a memory device are described. The memory controller may include a workload manager in communication with the memory device in which data is written and is read, the workload manager configured to acquire an amount of write data written to the memory device during a preset reference time, calculate a workload parameter indicating a ratio of the amount of write data to a reference write amount, and store the workload parameter for the preset reference time, and a performance manager configured to control, based on the workload parameter, a certain background operation performed by the memory device during a period corresponding to the workload parameter.

Dependent claims

A method of operating a memory controller, the memory controller controlling a memory device, the method comprising:

generating a plurality of time slots;
acquiring data amount information of a memory device based on data written to the memory device or read from the memory device, the data amount information corresponding to the plurality of time slots;
calculating workload parameters indicating differences between the data amount information and a reference data amount that is preset for the memory device;
storing the workload parameters respectively corresponding to the plurality of time slots;
and
controlling whether to perform a certain background operation of the memory device performed in each of the plurality of time slots based on the workload parameters.
