Abstract
An operating method for controlling a semiconductor memory device according to an embodiment may include storing read commands in a command queue managed on first-in first-out basis; providing one of the read commands to the semiconductor memory device; determining whether the provided read command passes or fails based on read data, which is provided from the semiconductor memory device in response to the provided read command; and aborting remaining read commands in the command queue when the provided read command passes.
Claims20
An operating method for controlling a semiconductor memory device, the operating method comprising:
- storing a plurality of read commands in a command queue managed on first-in first-out basis;
- providing one of the read commands to the semiconductor memory device;
- determining whether the provided read command passes or fails based on read data, which is provided from the semiconductor memory device in response to the provided read command;
- and
- aborting remaining read commands in the command queue when the provided read command passes.
A controller controlling a semiconductor memory device, the controller comprising:
- a command queue managed on first-in first-out basis;
- a command generation unit suitable for storing a plurality of read commands in the command queue;
- a memory control unit suitable for:
- providing one of the plurality of read commands to the semiconductor memory device;
- and
- determining whether the provided read command passes or fails based on read data, which is provided from the semiconductor memory device in response to the provided read command;
- and
- a command management unit suitable for aborting remaining read commands when the provided read command passes.
An operating method for controlling a semiconductor memory device including a plurality of pages, the operating method comprising:
- storing a plurality of commands for identifying data of a selected page in a command queue managed on first-in first-out basis;
- providing one of the commands to the semiconductor device;
- repeating the providing with remaining read commands when the provided read command fails;
- and
- aborting remaining read commands when the provided read command passes.
