Semiconductor device capable of performing a read leveling and a write leveling based on an ambient temperature

摘要

Disclosed herein is an apparatus that includes a first semiconductor chip including a first electrode, and a second semiconductor chip including a second electrode connected to the first electrode. One of the first and second semiconductor chips includes a first temperature sensor circuit generating a first detection signal, the first detection signal taking a first level when a temperature is equal to or higher than a first temperature, the first detection signal taking a second level when the temperature is lower than the first temperature; and a first delay code generation circuit outputting a first delay code signal in response to the first level of the first detection signal, and outputting a second delay code signal different from the first delay code signal in response to the second level of the first detection signal.
