Abstract
Disclosed herein are devices, methods, and systems for calibrating a sensing capacitance value used by a sensing circuit when reading memory cells of a memory. The calibration circuit includes a calibration cell associated with a predefined programming state of the calibration cell. The calibration circuit also includes a read circuit configured to perform a read operation on the calibration cell that generates a calibration voltage based on the predefined programming state and convert the calibration voltage to a target capacitance value based on the calibration voltage. The read circuit is configured to provide the target capacitance value to the memory as the sensing capacitance for the sensing circuit to use when reading the memory cells of the memory.
