In 2011, Apple acquired Anobit, an Israeli flash memory controller designer.

Four years later, it looks like they might now have something to show for it—thanks to Anandtech's report that the MacBook's SSD looked a little unusual in the system profiler, we took our heat gun to the SK Hynix SDRAM to see what was hiding underneath.

Where we expected to see something by Samsung or Toshiba, we found an unbranded chip with a very Apple-esque part number: 338S00055.

Our friends at ChipWorks took a peek, and have confirmed this is definitely an Apple custom device, fabricated at TSMC. We'll have more details soon!
