In what it termed a major step toward replacing conventional floating gate-based flash memories, Freescale Semiconductor announced the first production of 24-megabit (Mbit) memory array based on silicon nanocrystals. Silicon nanocrystal memories are part of an advanced class of memory technologies called thin-film storage. Freescale said they are more scaleable than conventional floating gate-based flash technology, as their tunnel oxide thickness can be reduced without impacting data retention. The charge is stored on isolated nanocrystals and...
