Abstract:
Circuits and methods for reading an OTP memory cell with improved reliability. To read a first OTP memory cell, a first current amount generated by a second, programmed, OTP memory cell is received. A second current amount generated by a third, unprogrammed, OTP memory cell is received. Current generated by the first OTP memory cell is sunk. The amount of current sunk from the first OTP memory cell is equal to a sum of a third current amount that is proportional to the first current amount plus a fourth current amount that is proportional to the second current amount. While sinking said current from the first OTP memory cell a voltage at a current output of the first OTP memory cell is compared to a threshold voltage.
