A highly reliable single-poly flash technology named ie-Flash (inverse gate electrode Flash), which can be embedded in a standard CMOS process without any process modifications, has been developed. The ie-flash cell consists of two elementary cells for OR-logical reading, resulting in significant improvement of reliability. 5 V-programming with 1 ms duration and 1.2 V-read operation of 35 bit memory modules fabricated by a 0.14 µ m CMOS process is demonstrated. This flash technology will extends not only testing cost reduction of the system-on-a chip by replacing laser-link but also provides flexibility of programmable logic applications.
