The 4-bit-per cell, 43nm chip.
The cooperative relationship between SanDisk and Toshiba in the development and manufacturing of advanced Flash memory is producing results with the companies announcing key technology advances at the International Solid State Circuits Conference (ISSCC) in San Francisco, California. The advances include the production of a 32-gigabit (Gb) 3-bits-per-cell (X3) memory chip that is expected to quickly enable greater capacities and reduce manufacturing costs for products ranging from memory cards to Solid State Drives (SSD). The companies also announced the fabrication of the world’s first 64Gb chip that applies 4-bit-per-cell (X4) technology without an increase in chip size, while achieving a write speed performance of 7.8MB/s.
