A method for generating a refresh signal includes measuring a temperature of the semiconductor memory device, generating a temperature controlled voltage based on the measured temperature, generating an N-bit digital signal based on the temperature controlled voltage, and generating a refresh signal whose frequency is determined by the N-bit digital signal. The generation of the temperature controlled voltage includes generating a first current that is increased when the measured temperature is decreased and is decreased with the measured temperature is increased, and generating the temperature controlled voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory device with optimum refresh cycle according to temperature variation","description":"Methods for generating a refresh signal in a semiconductor device and methods for performing a refresh operation in a semiconductor memory device are disclosed.
