Abstract
A method for outputting data error status of a memory device includes generating data status indication codes indicating error status of data chunks transmitted by a memory controller, and combining the data status indication codes with corresponding data chunks to generate an output signal, and outputting the output signal to a data bus pin.
Claims9
A method for outputting data error status of a memory device, comprising:
- generating, by a memory controller, a first data status indication code indicating error status of a first data chunk transmitted by the memory controller;
- generating, by the memory controller, a second data status indication code indicating error status of a second data chunk;
- combining, by the memory controller, the first data status indication code and the second data status indication code with the first data chunk and the second data chunk to generate an output signal, including:
- arranging the second data chunk immediately after the first data chunk;
- and
- arranging the second data status indication code immediately after the first data status indication code;
- and
- outputting, by the memory controller, the output signal to a data bus pin.

A method for outputting data error status of a memory device, comprising:
- generating, by a memory controller, a first data status indication code indicating error status of a first data chunk;
- determining, by the memory controller, whether the first data status indication code indicates a fail status;
- if so, generating a second data status indication code indicating the fail status, the second data status indication code being output immediately before or after a second data chunk to be output after the first data chunk;
- or
- if not, generating the second data status indication code indicating error status of the second data chunk;
- combining, by the memory controller, the first data status indication code and the second data status indication code with the first data chunk and the second data chunk to generate an output signal;
- and
- outputting, by the memory controller, the output signal to a data bus pin.
