Abstract
A nonvolatile memory device includes a target memory area; a control unit configured to apply a program pulse one or more times to the target memory area in response to a program command, until program verification passes; and a status storage unit configured to store a program status information for the target memory area, wherein the control unit is supplied with a first operation voltage, and the status storage unit is supplied with a second operation voltage.
Claims20
A nonvolatile memory device comprising:
- a control unit suitable for applying a program pulse to a target memory area of the nonvolatile memory device in response to a program command one or more times until a program verification passes;
- and
- a status storage unit suitable for storing a program status information of the target memory area;
- wherein the control unit is operable by a first operation voltage, and the status storage unit is operable by a second operation voltage.
1 more element
A data storage device comprising:
- a nonvolatile memory device;
- and
- a controller suitable for controlling the nonvolatile memory device,
- wherein the nonvolatile memory device includes:
- a control unit operable by a first operation voltage, and suitable for performing a program operation to a target memory area of the nonvolatile memory device;
- and
- a status storage unit operable by a second operation voltage separated from the first operation voltage, and suitable for storing a program status information for the target memory area while the program operation is performed.
4 more elements
A method for operating a data storage device, comprising:
- obtaining a status information from a nonvolatile memory device when it is determined that a program operation to a target memory area of the nonvolatile memory device is interrupted;
- and
- determining, based on the status information, whether to resume the program operation to the target memory area.
