Abstract
A data management method, a memory storage device and a memory control circuit unit. The method includes: executing one or more read commands, and recording a physical unit having a first variation of a read count greater than a read disturb threshold as a risk physical unit; and when a data merging process is performed, dividing valid data stored in the risk physical unit into a plurality of copies and copying the copies into a plurality of recycling units.
