What’s After NAND Flash?


By Mark LaPedus For years, many have predicted the end of flash memory scaling, particularly NAND, but the technology continues to defy the odds as it moves down the process curve. Still, there are signs that the floating gate structure in today’s flash memory is on its last legs. The floating gate is seeing an undesirable reduction in the control gate to capacitive coupling ratio. And ... » read more

Getting Ready For 15nm


By David Lammers The trends towards vertical transistors, non-silicon channel materials, and resistive RAMs promise to hold center stage at the 2010 IEEE International Electron Devices Meeting (IEDM), set to begin Dec. 6 in San Francisco, Calif. (www.ieee-iedm.org) Taiwan Semiconductor Manufacturing Co. (TSMC, Hsinchu, Taiwan) will present a 22/20nm technology platform based on a FinFET arc... » read more
