Abstract
A data search method, a memory storage apparatus, and a memory control circuit unit are provided. The method includes: detecting a boot signal; sending a first read command sequence based on a first grouping rule corresponding to grouping a first number of physical sub-units into one physical unit and then determining whether a system information of a rewritable non-volatile memory module is read; sending a second read command sequence based on a second grouping rule corresponding to grouping a second number of physical sub-units into one physical unit if the system information is not read; and operating the rewritable non-volatile memory module based on the system information. Therefore, the efficiency of searching for the system information from the rewritable non-volatile memory module can be improved.
