Just like with everything over time, technology will continue to advance and cause our devices to become more packed with intricate pieces of hardware. The modern smartphones require an unquenchable amount of raw power to sustain the ever growing insatiable appetite for memory. That's why SanDisk is continuing their efforts in the mobile space by announcing its latest MLC NAND chip which has four times the capacity of its 16GB modules that were offered just two years ago. There's a lot of stuff that is required in accomplishing this new feat, but it looks like the 64GB 32nm silicon flash drive is exactly the same as its older counterpart found in the X3 flash technology – essentially “innovations in flash management” allows each cell to hold three bits which can be used for boot, system code, and mass storage functions. In the end, they will be specifically designed for all of the advanced smartphones out there – providing a high capacity and reliable storage in a power-efficient package that has a relatively small footprint.
