Abstract: A memory controller coupled to a memory device and configured to control access operations of the memory device includes a host interface and a microprocessor. The microprocessor is coupled to the host interface and configured to set a value of a predetermined parameter to a specific value after the memory controller powers up and start to perform a link flow to try to establish a transmission link via the host interface. The predetermined parameter is one of a plurality of capability parameters of the host interface and the predetermined parameter is related to reception of the host interface. After the link flow is completed, the microprocessor is further configured to identify an object device with which the host interface establishes the transmission link according to the specific value and at least one of a plurality of attribute parameters associated with the transmission link.

Abstract: A method for performing communications specification version control of a memory device in predetermined communications architecture with aid of compatibility management, associated apparatus and computer-readable medium are provided. The method may include: utilizing a memory controller to receive a first command from a host device through a transmission interface circuit of the memory controller; utilizing the memory controller to execute a device-side compatibility management procedure of a compatibility management function to detect whether the host device conforms to any version of multiple predetermined versions of a predetermined communications specification according to the first command to generate a detection result, and selectively switch from one firmware version to another firmware version according to the detection result; and utilizing the memory controller to send a first response to the host device through the transmission interface circuit, wherein the first response is sent to the host device in response to the first command.
