Advanced NAND flash manufacturing processes await Apple’s approval

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.”

    1. More and more nouns are getting ‘verbed’. I work in an IT shop next to Solution Architects. They talk about ‘solutioning’ and ‘architecting’. Drives me nuts.

    2. According to the dictionary:

      transition |tranˈzi sh ən; -ˈsi sh ən|
      the process or a period of changing from one state or condition to another : students in transition from one program to another | a transition to multiparty democracy.
      • a passage in a piece of writing that smoothly connects two topics or sections to each other.
      • Music a momentary modulation from one key to another.
      • Physics a change of an atom, nucleus, electron, etc., from one quantum state to another, with emission or absorption of radiation.

      undergo or cause to undergo a process or period of transition : [ trans. ] the network ought to be built by the federal government and then transitioned into private industry | [ intrans. ] we have transitioned from a high-intensity combat operation to a support role in the community.

  1. This explains why iPods and iPads still max out at 64GB. Perhaps the smaller the manufacturing processes, the more likely it is that a part would fail, hence the longer approval process.
