In some embodiments a sensor is to sense a temperature of a memory occurring in the memory during active use of the memory. A controller is to adjust a voltage supply of the memory during active use of the memory in response to the sensed temperature. In some embodiments a monitor is to monitor errors occurring in a memory during active use of the memory, and a controller is to adjust a voltage supply of the memory during active use of the memory in response to the monitored errors. Other embodiments are described and claimed.
