512 Mb Flash Debuts New NAND Technology

The company's 512 Mb flash device launches as the industry's first NAND compatible flash chip based on TwinFlash technology. Developed by Saifun Semiconductors, TwinFlash technology stores two locally separated bits in one transistor cell. In contrast to single-bit-per-cell floating gate technologies with equivalent process structures, TwinFlash reports 40% smaller die sizes and less mask levels. Future permutations of the technology will feature wafer sizes of 110 nm and densities up to 2 Gb. The flash chip comes in a TSOP package and is aimed at removable solid state storage markets.
