Abstract
A data storage device includes a nonvolatile memory device; and a controller configured to include a plurality of cores, wherein, when an error occurs in at least one core among the cores, a first core which is coupled with the nonvolatile memory device transmits state records of one or more core among the cores at an error occurrence time, to the nonvolatile memory device.
Claims20
A data storage device comprising:
- a nonvolatile memory device;
- and
- a controller configured to include a plurality of cores,
- wherein, when an error occurs in at least one core among the cores, a first core which is coupled with the nonvolatile memory device transmits state records of one or more core among the cores at an error occurrence time, to the nonvolatile memory device.
A method for operating a data storage device, comprising:
- determining, by a controller, whether an error has occurred in a plurality of cores;
- collecting, when it is determined that an error has occurred, state records of one or more core among the cores at an error occurrence time, by a first core;
- and
- transmitting the state records to a nonvolatile memory device from the first core.
A method for operating a data storage device, comprising:
- determining, by a controller, whether an error has occurred in a plurality of cores;
- obtaining, when it is determined that an error has occurred, in a shared area in which data of the cores are stored, state records of one or more among the cores at an error occurrence time, based on the data;
- and
- transmitting the state records stored in the shared area, to a nonvolatile memory device from a first core.
The method according to claim 20, wherein the transmitting of the state records to the nonvolatile memory device from the first core comprises:
- obtaining, by the shared area, the state records for a predetermined time from a time when the interrupt command is received;
- and
- transmitting the obtained state records to the nonvolatile memory device from the first core.
