Data transmitting method, memory controller and data transmitting system

A memory controller for controlling a rewriteable non-volatile memory module, wherein the memory controller comprises:

• a host interface, configured to couple to a host system, wherein the host system is configured to execute a plurality of threads so as to transmit a plurality of commands to the memory controller via at least one human interface device (HID) interface, each of the commands corresponds to one of the threads, a plurality of packets are transmitted between the memory controller and the host system, the packets comply with a HID class, and each of the packets at least comprises a command series column and a data column;
• a memory interface, configured to couple to the rewriteable non-volatile memory module;
• and
• a memory management circuit, coupled to the host interface and the memory interface, configured to receive at least one command packet among the packets from the host system, wherein the command series column of the at least one command packet records a first command among the commands, the data column of the at least one command packet records a content of the first command,
• wherein the memory management circuit is configured to execute an operation corresponding to the first command at least according to the content of the first command so as to generate responding data, wherein the responding data is divided into at least one responding data packet among the packets,
• wherein the memory management circuit is configured to transmit a responding packet among the packets to the host system, wherein the command series column of the responding packet records the first command,
• wherein the memory management circuit is configured to transmit the at least one responding data packet to the host system, wherein the command series column of the at least one responding data packet records the first command,
• wherein the memory management circuit is configured to receive a retransmitting packet among the packets from the host system if a first responding data packet among the at least one responding data packet is lost, wherein the command series column of the retransmitting packet records the first command,
• wherein the memory management circuit is configured to retransmit the first responding data packet to the host system so as to response to the retransmitting packet.

A data transmitting system comprising:

• a host system;
• and
• a memory storage device,
• wherein the host system is configured to execute a plurality of threads so as to transmit a plurality of commands to the memory storage device via at least one human interface device (HID) interface, each of the commands corresponds to one of the threads, a plurality of packets are transmitted between the memory storage device and the host system, the packets comply with a HID class, and each of the packets at least comprises a command series column and a data column,
• wherein the memory storage device is configured to receive at least one command packet among the packets from the host system, wherein the command series column of the at least one command packet records a first command among the commands, the data column of the at least one command packet records a content of the first command,
• wherein the memory storage device is configured to execute an operation corresponding to the first command according to the content of the first command so as to generate responding data, wherein the responding data is divided into at least one responding data packet among the packets,
• wherein the memory storage device is configured to transmit a responding packet among the packets to the host system, wherein the command series column of the responding packet records the first command,
• wherein the memory storage device is configured to transmit the at least one responding data packet to the host system, wherein the command series column of the at least one responding data packet records the first command,
• wherein the host system is configured to determine if one of the at least one responding data packet is lost according to the responding packet,
• wherein if the host system determines that a first responding data packet among the at least one responding data packet is lost, the host system is configured to transmit a retransmitting packet among the packets to the memory storage device so as to request the memory storage device to retransmit the first responding data packet, wherein the command series column of the retransmitting packet records the first command,
• wherein the memory storage device is configured to retransmit the first responding data packet to the host system so as to response to the retransmitting packet.
