A temperature compensated RRAM sensing circuit to improve the RRAM readability
against temperature variations is disclosed. The circuit comprises a temperature
dependent element to control the response of a temperature compensated circuit
to generate a temperature dependent signal to compensate for the temperature variations
of the resistance states of the memory resistors. The temperature dependent element
can control the sensing signal supplied to the memory resistor so that the resistance
states of the memory resistor are compensated against temperature variations. The
temperature dependent element can control the reference signal supplied to the
comparison circuit so that the output signal provided by the comparison circuit
is compensated against temperature variations. The temperature dependent element
is preferably made of the same material and process as the memory resistors.
