Abstract
A controlling method, a channel operating circuit and a memory system for executing a plurality of memory dies with single channel are provided. The plurality of memory dies correspond to a plurality of queue sections of a command queue. The controlling method comprises the following steps: A selecting unit selects one of the plurality of queue sections corresponding one of the plurality of memory dies which is riot at a busy state. An executing unit executes a command stored in one of the plurality of queue sections which is selected.

A controlling method for executing a plurality of memory dies with single channel, wherein the plurality of memory dies corresponds to a plurality of queue sections of a command queue, and the controlling method comprises:
- selecting, by a selecting unit, one of the plurality of queue sections which is not at a busy state;
- and
- executing, by an executing unit, a command stored in the one of the plurality of queue sections which is selected.
A channel operating circuit, for executing a plurality of memory dies with single channel, wherein the channel operating circuit comprises:
- a command queue including a plurality of queue sections, which correspond the plurality of memory dies;
- a selecting unit for selecting one of the plurality of queue sections which is corresponding one of the plurality of memory dies which is not at a busy state;
- and
- an executing unit for executing a command stored in one of the plurality of queue sections which is selected.
A memory system, comprising:
- a plurality of memory dies;
- and
- a controller, including:
- a memory interface circuit, including at least one channel operating circuit for executing the plurality of memory dies with single channel, wherein the channel operating circuit comprises:
- a command queue including a plurality of queue sections, which correspond the plurality of memory dies;
- a selecting unit for selecting one of the plurality of queue sections corresponding one of the plurality of memory dies which is not at a busy state;
- and
- an executing unit for executing a command stored in one of the plurality of queue sections which is selected.
