Abstract
This application discloses a memory device to retain stored data when receiving a voltage supply having at least a retention voltage level. The retention voltage level varies based on a supply voltage and a temperature of an environment around the memory device. A sensitive circuit can adjust the voltage supply received by the memory device based on the supply voltage and the temperature. The sensitive circuit can alter a memory bias supply voltage for the memory device to adjust the voltage supply towards the retention voltage level. The sensitive circuit can include a temperature dependent circuit to generate a bias voltage based on the supply voltage and the temperature, and an adjustment circuit to alter the memory bias supply voltage based on the bias voltage. The adjustment circuit also can include high temperature circuitry to adjust the memory bias supply voltage based on a leakage current from the memory device.
