Not content with simply matching the Micron / Intel effort, SanDisk and its partner Toshiba claim their new memory uses 19- rather than 20-nanometer cells in the production process. Shrinking the size is one thing, but SanDisk's new chips also use its X3 / three-bit technology. Most memory stores just two bits per cell; cramming in another means fewer cells, less silicon, more savings, cheaper memory, happier geeks. Analyst Jim Handy estimates that the price per gigabyte for the tri-bit breed of flash could be as l
