ABSTRACT:
A self-refresh module includes an oscillator configured to provide a first signal having a first frequency, a trimming divider configured to trim the first signal to provide a second signal having a second frequency, and a temperature sensor configured to sense a temperature of the memory device and provide a temperature signal. The self-refresh module includes a temperature look-up table configured to receive the temperature signal and provide a third signal based on the temperature signal, and a temperature divider configured to provide a self-refresh pulse signal based on the second signal and the third signal.
