Embodiment Construction

[0058] figure 1 A programmable integrated circuit chip 100 with programmable circuit blocks according to an embodiment of the present invention is shown. Such as figure 1 As shown, the programmable integrated circuit chip 100 includes a circuit block 110 connected to an OTP memory 120.

[0059] The circuit block 110 includes logic for performing one or more functions of the programmable integrated circuit chip 100. For example, this function may include providing a reference voltage or performing power sequencing functions. However, these examples are not a limitation of the present invention, and those of ordinary skill in the art can easily understand that the circuit block 100 can also perform many other functions.

[0060] The OTP memory 102 includes one or more OTP storage units. These OTP memory cells can be arranged as an array or as one or more cell groups. Each OTP memory cell includes a non-volatile memory element and a fuse element. The storage element can store logi...

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).

Description

Technical field [0001] The present invention relates to an integrated circuit chip, and more specifically, the present invention relates to an integrated circuit chip with programmable functions and characteristics. Background technique [0002] During and / or after the manufacture of integrated circuit chips, it is often desirable to be able to change their functions and characteristics. In order to do this, the chip can be designed by using on-chip memory to program these characteristics. Usually, through, for example, metal fuses and / or electrically erasable programmable read-only memory (E 2 PROM) to realize the on-chip memory required by this programmability. [0003] For example, metal fuses have been used to adjust precise reference voltage sources in silicon chips. Metal fuses usually occupy a relatively large area in the silicon chip, which limits the number of fuses that can be included on a single chip. Due to this limitation, the programmability achieved using this met...
