Abstract:
At least one MOS parameter of a MOS fuse (200) is characterized to provide at least one MOS parameter reference value. Then, the MOS fuse (200) is programmed by applying a programming signal to the fuse terminals (204, 206) so that programming current flows through the fuse link (202). The fuse resistance is measured to provide a measured fuse resistance associated with a first logic value. A MOS parameter of the programmed MOS fuse is measured to provide a measured MOS parameter value. The measured MOS parameter value is compared to the reference MOS parameter value to determine a second logic value of the MOS fuse, and a bit value is output based on the comparison.
Abstract:
A memory cell with a logic bit has a first one-time-programmable ("OTP") memory element providing a first OTP memory element output and a second OTP memory element providing a second OTP memory element output. A logic operator coupled to the first OTP memory element output and to the second OTP memory element output and provides a binary memory output of the memory cell. In a particular embodiment, the first OTP memory element is a different type of OTP memory than the second OTP memory element.
