Abstract
The present disclosure provides a dynamic random-access memory (DRAM) with a data correction function and a method of operating the same. The DRAM includes a memory array; a control circuit configured to receive an inputting data and a temperature signal; a first error-correction code (ECC1) circuit configured to generate a first encoded data from the inputting data; and a second error-correction code (ECC2) circuit configured to generate a second encoded data from the inputting data.

A dynamic random-access memory (DRAM), comprising:
- a memory array;
- a control circuit configured to receive an inputting data and a temperature signal;
- a first error-correction code (ECC1) circuit configured to generate a first encoded data from the inputting data;
- and
- a second error-correction code (ECC2) circuit configured to generate a second encoded data from the inputting data.
A dynamic random-access memory (DRAM), comprising:
- a memory array;
- a control circuit configured to receive an inputting data and a temperature signal;
- a first error-correction code (ECC1) circuit configured to generate a first encoded data from the inputting data;
- and
- a second error-correction code (ECC2) circuit configured to generate a second encoded data from the inputting data, wherein the ECC1 circuit is enabled when the temperature signal indicates that an ambient temperature is lower than a threshold temperature and the ECC2 circuit is enabled when the temperature signal indicates that the ambient temperature is higher than the threshold temperature.
A method of operating a dynamic random-access memory, comprising the steps of:
- receiving an inputting data;
- receiving a temperature signal;
- interpreting the temperature signal indicating an ambient temperature;
- determining whether the ambient temperature is lower than a threshold temperature;
- and
- enabling one of at least two error-correction code circuits based on the determining result.
