Abstract: A method for performing access control between a host device and a memory device, an associated bridge device and a bridge controller thereof are provided, where the method is applicable to the bridge device for coupling the memory device to the host device. The method may include: receiving a first test command; returning failure information; receiving a request command; returning device-related information; receiving a second test command; returning pass information; receiving a capacity-related command; reporting a reported logical address (LA) count of the memory device and a reported sector size of the memory device; and performing bi-directional mapping between a memory device side LA format of a set of LAs at the memory device side corresponding to the memory device and a host device side LA format of a set of LAs at the host device side corresponding to the host device during access operation that the host device performs.
