Volatile memory and one-time program (OTP) compatible memory cell and programming method
A volatile and one-time program (OTP) compatible asymmetric memory cell may include a first pull-up transistor having a first threshold voltage. The asymmetric memory cell may also include a second pull-up transistor having a second threshold voltage that differs from the first threshold voltage. The asymmetric memory cell may further include a switch coupled to a well of the first pull-up transistor and the second pull-up transistor to alternate between a program voltage (Vpg) and a power supply voltage. The asymmetric memory cell may also include a peripheral switching circuit to control programming of the asymmetric memory cell.
