Abstract
A mapping table management method, a memory control circuit unit, and a memory storage device are provided. The method includes: receiving a read command from a host system, wherein the read command indicates reading a first data stored in at least one first logical address; and searching whether a relation management information reflects that a first group static mapping table recording the first logical address is related to a dynamic mapping table. In response to a search result reflecting that the first group static mapping table is related to the dynamic mapping table, the dynamic mapping table is searched to obtain a first physical address mapped by the first logical address. And if not related, the first group static mapping table among group static mapping tables is searched to obtain a second physical address mapped by the first logical address.
