Abstract
A method for performing access management in a memory device, the associated memory device and the controller thereof, and the associated electronic device are provided. The method may include: receiving a host command and a logical address from a host device; performing a checking operation to obtain a checking result, for determining whether to load a logical-to-physical (L2P) table from the NV memory to a random access memory (RAM) of the memory device; reading the target data and associated metadata from the NV memory, wherein a latest version of the L2P table is available in the RAM when reading the target data from the NV memory is performed; and checking whether a recorded logical address within the metadata and the logical address received from the host device are equivalent to each other, to control whether to send the target data to the host device.
