Abstract
A solid state drive (SSD) includes an NAND memory and an SSD controller. The SSD controller includes an interface coupled to a host machine, a nonvolatile memory controller coupled to the interface, and a processor coupled to the nonvolatile memory controller. The SSD controller is configured to: receive, via the interface, a write command from the host machine; process, by the nonvolatile memory controller, the write command; transmit, from the nonvolatile memory controller to the processor, a system message; process, by the processor according to Zoned Namespaces (ZNS) protocol, the system message; obtain, by the nonvolatile memory controller via the interface, host data for storage from the host machine; and write the host data to the NAND memory based on a result of processing the system message. Processing the system message by the processor and obtaining the host data by the nonvolatile memory controller are executed in parallel.
