Apple rumored to feature high-speed 400MBps flash memory in new MacBook AirApple is said to adopt "Toggle DDR 2.0," a 19-nanometer process for NAND flash memory offering 400 megabyte-per-second speed, in its next MacBook Air, according to a new report.
The high-speed NAND flash memory is said to appear in Apple's new MacBook Air, rumored to see an imminent release, according to Macotokara. Citing a person with an "Asian electronics component company," the report said that the new technology will replace the Blade X-gale found in the current MacBook Air models.
The new 19-nanometer flash memory is said to be packaged on a smaller chip, and will be soldered onto the base circuit of the new thin-and-light notebook directly.
The report noted that the Open NAND Flash Interface Working Group, which standardizes NAND flash, has released the ONFi 3.0 specification for 400MBps speeds, but most memory processing companies do not yet offer compatible chips. It said that "Toggle DDR 2.0," which is a standardized procedure from the JEDEC Solid State Technology Association, is believed to have been embraced by Apple.
Apple's MacBook Air was made thinner and lighter with a new model released last October that features instant-on capabilities with no hard drive and no optical drive. The ultraportable notebook sports only NAND flash memory for storage.
That storage was initially provided by Toshiba, but later changed to Samsung. The change allowed for read times to be upgraded to 261.1MBps, from 209.8Mbps, while write times were boosted to 209MBps from 175.6MBps.
Rather than relying on traditional 2.5-inch or 1.8-inch SSDs, the new MacBook Air drives utilize a new form factor known as mSATA. After the thinner and lighter MacBook Air was unveiled last year, Toshiba announced its Blade X-gale SSD series, the same hardware found in Apple's thin-and-light notebook.
Apple is said to have built nearly 400,000 of its next-generation MacBook Air last month in preparation for a launch that is expected to occur soon. The anticipated new notebooks are believed to feature Intel's latest Sandy Bridge processors, as well as the new high-speed Thunderbolt port.
While new MacBook Air hardware is expected to launch soon, it will not debut until Apple's next-generation operating system is released. AppleInsider was first to report last month that Apple would freeze the introductions of new Mac hardware until Mac OS X 10.7 Lion is released. The "Golden Master" of Lion was released to developers last week.
