Nonvolatile memory controller with host controller interface for retrieving and dispatching nonvolatile memory commands in a distributed manner

摘要

A nonvolatile memory controller includes a host controller interface, processors, a message networks and a data network. The host controller interface includes a command fetch module, command assembly buffers, and a command dispatch module. The command fetch module retrieves nonvolatile memory commands from a host processing unit. The command assembly buffers store the nonvolatile memory commands retrieved from the host processing unit. The command dispatch module generates request message packets including the nonvolatile memory commands. The message network routes the request message packets to the processors. The processors process the nonvolatile memory commands in the request message packets for controlling operation of the nonvolatile memory controller.
