Abstract:
Junction diodes fabricated in standard CMOS logic processes can be used as program selectors for One-Time Programmable (OTP) devices, such as electrical fuses. At least one portion of the electrical fuse can have at least one extended area to accelerate programming. An extended area is an extension of the fuse element beyond contact or via longer than required by design rules. The extended area also has reduced or substantially no current flowing through. The program selector can be at least one MOS. The OTP device can have the at least one OTP element coupled to at least one diode in a memory cell.
