Abstract
A data management method for a solid state storage device is provided. The solid state storage device can selectively perform a TACW operation. While the TACW operation is performed, the controlling circuit determines a specified time interval corresponding to the largest amount of write data. Moreover, a portion of the write data stored in the specific time interval will be moved to another location of the non-volatile memory. When the solid state storage device performs the data remediation process according to the data retention time, the time period of performing the data remediation process is largely shortened. Consequently, the performance of the solid state storage device can be enhanced.
