Abstract
A memory system includes: a memory device; and a controller suitable for controlling the memory device and including a buffer memory, wherein the controller performs error history logging into the buffer memory in response to a logging start command from a host, stops the error history logging in response to a logging stop command from the host, and provides the host with the logged error history in response to an output command from the host.
Claims19
A memory system comprising:
- a memory device;
- and
- a controller suitable for controlling the memory device and including a buffer memory,
- wherein the controller performs error history logging into the buffer memory in response to a logging start command from a host, stops the error history logging in response to a logging stop command from the host, and provides the host with the logged error history in response to an output command from the host.

An operating method of a memory system, comprising:
- performing error history logging into a buffer memory, included in the memory system, in response to a logging start command from a host;
- stopping the error history logging in response to a logging stop command from the host;
- and
- providing the host with the logged error history in response to an output command from the host.
1 more element
A system comprising:
- a host;
- and
- a memory system including a memory device and a controller including a memory,
- wherein the controller is configured to:
- receive a first error history command from the host;
- trigger error history logging in response to the first error history command such that errors that occur in the system are logged in the memory, wherein each error logged in the memory as associated with at least one of command information regarding one or more commands for the memory device and state information of the memory system at the time the corresponding error occurred;
- receive a second error history command from the host;
- and
- provide the host with the error history in response to the second error history command.
