Hynix Semiconductor has developed the world¡¯s first 32-gigabyte NAND flash memory using ¡°three-bit-per-cell¡± or X3 technology, the firm said Tuesday. A cell is the smallest storage unit, and the cutting edge three-bit technology allows three pieces of information to be stored in one unit. This will decrease production cost of semiconductor products by a large margin as it reduces the size of chips by 30 percent compared to those made with two-bit-per-cell technology, which is widely used in the business at the moment.
With the technology, the world¡¯s second largest chipmaker plans to produce 32-gigabyte products with nano technology which has been applied only to making 16-gigabyte products, from October. (1 nanometer = one-billionth of a meter) ¡°When storage capacity per cell expands, there can be a problem which causes stored information to get entangled. We overcame this obstacle and completed developing three-bit-per-cell technology, which laid the groundwork for reducing production costs,¡± a Hynix official said.
