Samsung develops 256GB smartphone memory chip

SEOUL -- Samsung Electronics  has introduced a new version of its advanced smartphone memory device with double the capacity of existing models.

     The South Korean electronics maker now produces a 256-gigabyte memory device using its Universal Flash Storage standard. A 128GB device, previously the largest available using the technology, debuted in February 2015.

     The latest version of UFS, incorporating 3-D NAND flash memory and a controller component, allows data to be read at 850 megabytes per second -- more than triple the speed from the earlier embedded MultiMedia Card technology built on memory alone. Data can be written from a smartphone itself to the memory device at 260Mbps, over twice the speed of eMMC.

     UFS devices are around the same size as their eMMC equivalents. No price has been set yet for the 256GB model.
