Claim 0:
1. A method for performing link management of a memory device in a predetermined communications architecture with aid of handshaking phase transition control, the method being applied to a memory controller of the memory device, the memory device comprising the memory controller and a non-volatile (NV) memory, the NV memory comprising at least one NV memory element, the method comprising:
utilizing at least one upper layer controller of a transmission interface circuit within the memory controller to turn on a physical layer (PHY) circuit of the transmission interface circuit, for starting establishing a link between a host device and the memory device;
before entering a first handshaking phase of a handshaking procedure of the memory device, the handshaking procedure for establishing the link between the host device and the memory device, utilizing the PHY circuit to receive any first incoming data sent from the host device to determine whether the any first incoming data indicates that the host device is in a corresponding first handshaking phase, and prevent sending any outgoing data that is equal to first predetermined data of the first handshaking phase to the host device before detecting that the host device is in the corresponding first handshaking phase, wherein the first handshaking phase is not earliest among multiple handshaking phases of the handshaking procedure; and
in response to the any first incoming data indicating that the host device is in the corresponding first handshaking phase, utilizing the PHY circuit to send first outgoing data that is equal to the first predetermined data to the host device.
