Method for performing data access management of memory device in predetermined communications architecture with aid of unbalanced table regions, memory controller of memory device, memory device, and electronic device

A method for performing data access management of a memory device in a predetermined communications architecture with aid of unbalanced table regions may include: utilizing a memory controller to receive a first command from a host device through a transmission interface circuit, where the first command carries first information related to first data to be written; performing a first checking operation on the first information to generate a first determination result; determining a selected active block among multiple active blocks according to the first determination result and according to at least one predetermined rule; and receiving the first data with the selected active block, and updating a temporary physical-to-logical (P2L) address mapping table corresponding to the selected active block among multiple temporary P2L address mapping tables of different sizes, for generating/updating P2L address mapping table for performing subsequent processing.
