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.
