AI Technical Summary

Benefits of technology

The present disclosure is related to a semiconductor apparatus that includes a temperature detecting circuit and a temperature raising circuit. The temperature detecting circuit can detect temperature and generate temperature detection information, while the temperature raising circuit can generated heat based on the temperature detection information. The semiconductor memory apparatus can also include a command decoding circuit, a temperature detecting circuit, a refresh control circuit, and a memory bank circuit. The command decoding circuit can generate an internal refresh command signal based on an external command signal. The temperature detecting circuit can detect temperature and generate temperature detection information. The refresh control circuit can generate a refresh control signal based on the internal refresh command signal during a refresh operation and based on the temperature detection information during a heating operation. The memory bank circuit can perform a refresh operation based on the refresh control signal. This arrangement allows for efficient heating control in the semiconductor memory apparatus and improves refresh performance.

Problems solved by technology

Especially, an extremely low temperature in a winter can cause malfunction of the electronic parts mounted in the vehicle.

The malfunction of the electronic parts mounted in the vehicle is suspected as a main cause of the sudden unintended acceleration of the vehicle.
