SanDisk makes 128-gigabit flash chip, crams three bits per cell, takes afternoon off

SanDisk has developed a chip that earns it membership in the exclusive 128-gigabit club . 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 low as 28 cents, compared to 35 for the Micron / Intel equivalent.
