2) The On-Chip Temperature Sensor (OCTS) adjusts the refresh rate in self refresh mode to the component’s actual
temperature with a much finer resolution than supported by the 4 distinct temperature levels as defined by JEDEC for
TCSR. At production test the sensor is calibrated, and IDD6 max. current is measured at 85°C. Typ. values are obtained
from device characterization.
