eMemory Technology Inc. disclosed that it has made available the technology of 0.13?m Neobit programmable embedded non-volatile memory in logic process, which is advanced to higher level through low-k copper process.

With a simple structure, the Neobit OTP embedded non-volatile memory is not only fully compatible with any current cmos process but is also able to design in without extra mask layer or changing existing CMOS behaviors. As the CMOS technology progresses, device margin is scaled. It is therefore difficult to embed traditional CMOS process with non-volatile memory cell because of extra thermal budget and additional mask layers, said the company. However, Neobit utilizes the pure CMOS devices as its cell element and does not change original CMOS device schemes.

The Neobit OTP is successfully applied to 0.5-, 0.35-, 0.25- and 0.18?m process mass production. In addition to logic process, collaboration with foundries has been extended to various manufacturing processes such as high-voltage process, SiGe process, radio frequency process and mixed-signal process.

The 0.13um Neobit IP provides the memory density from couples of bits to 1Mb. For shooting kinds of application, Neobit IP offers the read schemes with single (1.2V) or dual (1.2V/3.3V or 1.2V/2.5V) operation voltages. In addition, Neobit IP allows the programming operation done by external programming voltage source or internal charge pumping circuit. The 0.13um Neobit cell performs the programming operation with programming voltage below 6V and programming speed below 100?s for bit-by-bit, byte-by-byte or word-by-word programming. For low bit count applications, IPs featuring equivalent functionality as conventional laser fuse or electrical fuse, are available.

To date, eMemory said, the 0.13?m Neobit has been verified by leading foundries and is able to provide prototypes to its customers worldwide.
