Abstract
An integrated circuit chip having programmable functions and features in which one-time programmable (OTP) memories are used to implement a non-volatile memory function, and a method for providing the same. The OTP memories may be based on poly-fuses as well as gate-oxide fuses. Because OTP memories are small, less die area is utilized as compared to metal fuses. Addtionally, because OTP memories can be implemented as part of standard complementary metal oxide semiconductor (CMOS) processes, the method is less costly and complex than the use of electrically-erasable programmable read-only memories (E2PROMs).
