NVME Data Processing Method and NVME Device

A Non-Volatile Memory Express (NVMe) data processing method, the method being performed by an NVMe device, the NVMe device comprising a solid state drive (SSD) controller, a transceiver, a submission queue (SQ) cache and a completion queue (CQ) cache, and the method comprising:

• obtaining, by the transceiver, an NVMe command, the SSD controller comprising an SQ control circuit and a CQ control circuit, the SQ cache being configured to store an SQ, the CQ cache being configured to store a CQ, the SQ control circuit being configured to manage the SQ, and the CQ control circuit being configured to manage the CQ;
• writing, by the transceiver, the NVMe command into the SQ;
• sending, by the SQ control circuit, the NVMe command in the SQ to the SSD controller in response to a change of the SQ in the SQ cache;
• executing, by the SSD controller, the NVMe command;
• writing, by the SSD controller, a generated NVMe command response into the CQ;
• and
• instructing, by the SSD controller, a host to read the NVMe command response in the CQ.
