Systems and Methods for Decoupling Host Commands in a Non-Volatile Memory System

A non-volatile memory system comprising:

• a non-volatile memory;
• and
• a controller in communication with the non-volatile memory, the controller configured to:
• translate a first command that is formatted according to a communication protocol to a second command that is formatted generically;
• store the first command in an expected queue;
• store the second command in the expected queue with a command priority;
• select the second command for execution based on the command priority;
• translate a result of the executed second command into a format according to the communication protocol;
• and
• transmit the result of the executed second command in the format according to the communication protocol to a host system dependent upon a position of the first command in the expected queue.

With a controller of a non-volatile memory system, a method comprising:

• receiving, from a host system coupled to the non-volatile memory system, a host command;
• translating the host command into at least a first memory command and a second memory command;
• determining a command priority in a first expected queue of a plurality of expected queues for the first memory command and determining a command priority in the first expected queue for the second memory command;
• selecting the first memory command for execution based on a priority of the first expected queue and the command priority of the first memory command;
• selecting the second memory command for execution based on the priority of the first expected queue and the command priority of the second memory command;
• translating a result of an execution of the first memory command and an execution of the second memory command into a formatted host command based on a format of the host command;
• and
• transmitting the formatted host command to the host system.

A non-volatile memory system comprising:

• a non-volatile memory;
• means for translating a first command that is formatted according to a communication protocol to a second command that is formatted generically;
• means for storing the first command in an expected queue;
• means for storing the second command in the expected queue with a command priority;
• means for selecting the second command for execution based on the command priority;
• means for translating a result of the executed second command into a format according to the communication protocol;
• and
• means for transmitting the result of the executed second command in the format according to the communication protocol to a host system dependent upon a position of the first command in the expected queue.
