Abstract
A memory device includes a write error check circuit suitable for detecting an error in received data using an error correction code during a write operation; and a memory core suitable for storing the received data and the received error correction code when no error is detected by the write error check circuit.
Claims19
A memory device comprising:
- a write error check circuit suitable for detecting an error in received data, transferred from a memory controller, using a received error correction code, transferred from the memory controller, during a write operation;
- and
- a memory core suitable for storing the received data and the received error correction code that is used for detecting the error in the received data when no error is detected by the write error check circuit,
- wherein, when an error in the received data is detected by the write error check circuit during the write operation, the received error correction code and the received data are not stored in the memory core.

A memory system including a memory device and a memory controller,
- the memory device comprising:
- a write error check circuit suitable for detecting an error in data, received from the memory controller using an error correction code received from the memory controller during a write operation;
- and
- a memory core suitable for storing the received data and the received error correction code that is used for detecting the error in the data when no error is detected by the write error check circuit,
- the memory controller comprising:
- an error correction code generation circuit suitable for generating the error correction code to be transferred to the memory device using the data to be transferred to the memory device;
- and
- an error correction circuit suitable for correcting, when an error is present in data transferred from the memory device, the error in the data transferred using an error correction code transferred from the memory device,
- wherein, when an error in the received data is detected by the write error check circuit during the write operation, the received error correction code and the received data are not stored in the memory core.
6 more elements
A method for operating a memory system, comprising:
- generating, by a memory controller, an error correction code using write data;
- transferring a write command, the write data, and the error correction code to a memory device from the memory controller;
- detecting, by the memory device, an error in the write data using the error correction code;
- storing, when no error in the write data is detected, the write data and the error correction code that is used for detecting the error in the write data, in a memory core of the memory device;
- and
- not performing a write operation by the memory device and notifying the memory controller that an error in the write data is detected, when the error in the write data is detected.
