Abstract
A memory system includes: a controller for selecting a pre-coding mode or a normal write mode in response to a host interface mode change command inputted from a host device; and a semiconductor memory device for storing, in an operating system (OS) storage area, OS data inputted from the host device in the pre-coding mode under the control of the controller.
Claims16
A memory system comprising:
- a controller configured to change a host interface mode for communicating with a host device in response to a host interface mode change command inputted from the host device and to select a pre-coding mode or a normal write mode in response to the host interface mode change command;
- and
- a semiconductor memory device configured to store, in an operating system (OS) storage area, OS code data inputted from the host device in the pre-coding mode under the control of the controller,
- wherein the controller enables the pre-coding mode in initial setting, and maintains a state of the pre-coding mode during an initial setting operation as an enable state when the host interface mode change command corresponds to a high-speed mode.

A method for operating a memory system, the method comprising:
- selecting a host interface mode for communicating with a host device in response to a host interface mode change command inputted from the host device;
- selecting a pre-coding mode or a normal write mode according to the host interface mode change command;
- and
- storing data inputted from the host device in a semiconductor memory device in the pre-coding mode or the normal write mode,
- wherein the semiconductor memory device includes a plurality of memory blocks, and some memory blocks among the plurality of memory blocks are defined as an OS storage area for storing OS code data in the pre-coding mode, and the other memory blocks except the OS storage area among the plurality of memory blocks are defined as normal memory blocks, and
- wherein, when a number of empty memory blocks of the OS storage area is insufficient in the pre-coding mode, the OS code data is stored in the normal memory blocks.
