Abstract

The present invention provides a memory controller and data storage system. The memory controller is configured to perform multiple steps: in response to a first parameter of a register being updated, switching a default mode to a specified mode; reading a second parameter of the register to determine a specified threshold; obtaining status information of a physical unit according to the specified mode; and, if the status information of the physical unit meets the specified threshold, executing a data consolidation procedure on the memory according to the specified mode. In this manner, the memory controller operates in different modes to execute the data consolidation procedure in different scenarios.
