Universal Memory
is now driving force in semiconductor industry
Flash memory
devices based on polycrystalline silicon floating gate and silicon nitride
(silicon- oxide- nitride- oxide- silicon, or SONOS/TANOS structures) as memory
layer according to projections will replace in future magnetic and optical
memory (see figure from paper
of S. M. Sze,
Evolution of Nonvolatile Semiconductor Memory: From Floating-Gate to
Single-Electron Memory Cell, in “Future Trends in Microelectronics”,
Edited by S. Luryi,
J. Xu,
and A. Zaslavsky,
