Sam Oliver reports for AppleInsider, “Makers of NAND flash memory found in devices like the iPhone and iPad have worked to transition their manufacturing processes to below 30nm, but the products have yet to be certified by the largest user of NAND flash: Apple.”
“Both Samsung Electronics and Toshiba have made products that are sub-30nm, sources told DigiTimes,” Oliver reports. “The move to more advanced NAND production methods only makes sense if volume production can be achieved with companies like Apple buying the memory.”
Oliver reports, “The transition has reportedly been held up because of longer certification times. While customers like Apple approved 30nm-class NAND flash in three to six months, validation now takes as long as nine months. Current industry standards have more stringent requirements for product performance, quality and reliability, sources told the Taiwanese industry publication.”
