Samsung Semiconductor continues to pack data more into solid-state storage, announcing Tuesday a new generation of its V-NAND technology that should help bring down the cost and power consumption of flash later this year. The first 3-bit version of its 3D V-NAND (Vertical NAND) flash, it fits one more bit of data on each layer of the stacked technology. Bob Brennan, vice president of Samsung Semiconductor's memory solutions lab, expects an SSD (solid-state drive) using the new technology to ship by the end of this year.
