The microFlash (NROM) concept is a 2-bit memory cell using an ONO dielectric as a storage media. To establish the capabilities and applications of the technology, endurance tests were performed on a 2Mb device. No limitation was found to cycle the device to 10,000 cycles and beyond. The microFlash process has been qualified ad implemented in production for applications requiring a limited number of program-erase cycles. The pbjective of the described work was to significantly increase the number of cycles. R&D is in progress to qualify the device for 10,000 cycles.
