Abstract
Provided herein may be a memory system and a method of operating the same. The method of operating a memory system may include receiving a first program command, and performing an operation corresponding to the first program command, receiving a second program command while performing the operation corresponding to the first program command, delaying setting of a queue status register for the second program command by a first wait time, receiving a third read command before the first wait time elapses, and setting the queue status register for the third read command before setting the queue status register for the second program command.

A method for a memory controller controlling a non-volatile memory device, the method comprising:
- receiving a plurality of commands from a host;
- queueing a command among the plurality of commands into a queue status register based on a priority of the plurality of commands;
- and
- executing a next command among the plurality of commands to be performed after the command based on the priority of the plurality of commands and a category of the plurality of commands,
- wherein the queueing comprises:
- setting a status of the command as a set status;
- and
- setting the status of the command as a clear status after the memory device starts to perform an operation corresponding to the command.
An apparatus, comprising:
- a memory device;
- and
- a controller coupled to the memory device and configured to:
- receive a plurality of commands from a host;
- queue a command among the plurality of commands into a queue status register based on a priority of the plurality of commands;
- set a status of the command as a set status;
- set the status of the command as a clear status after the memory device starts to perform an operation corresponding to the command;
- and
- execute a next command among the plurality of commands to be performed after the command based on the priority of the plurality of commands and a category of the plurality of commands.
