Abstract
A refresh control circuit and method generates a refresh signal in response to one of a plurality of clock signals and a temperature signal. The clock signals and temperature signal may be synchronized to prevent an incomplete refresh operation at a trip point of a temperature sensor. In one embodiment, a pulse generator may generate a temperature sensor enable signal in response to the clock signals when the clock signals are synchronized. In other embodiments, the temperature signal may be latched to prevent a transition in the refresh signal during a refresh operation. The temperature signal may be latched in response to one of the clock signals or the refresh signal.
