Apple To Adopt “Toggle DDR 2.0” 19nm Process NAND Flash Memory For The Revised MacBook Air – Rumor

The Japanese Apple-focused blogsite Macotakara says that according to an unnamed Asian electronics component company person, Apple appears to be fixing to adopt the 400-Mbps interface “Toggle DDR2.0,” a 19-nanometer process for NAND flash memory for new MacBook Air. Since its major revision in October, 2010, the Air has used only NAND drives for data storage.

Macotakara speculates that the current SSD device Blade X-gale, supporting SATA 2.6, that is used in the current MacBook Air models, will be dropped, and new 19nm flash memory will be packaged into smaller chip and will be soldered directly to the motherboard.

The Open NAND Flash Interface Working Group, NAND technology’s standardization organization, has already released ONFi 3.0, the report says. That standard supports 400Mbps specifications like Toggle DDR2.0, but the top 70% of NAND processing companies, including Samsung (36.9%) and Toshiba (35.1%)m as of the first quarter of 2011 had not joined on this ONFi.

Toggle DDR2.0 is a standardized procedure defined by JEDEC (Global Standards for the Microelectronics Industry), and Macotakara says JEDEC seems to have Apple’s support.

If this rumor is accurate, it’s already a fait-accompli. Apple is believed to have already stockpiled 400,000 next-generation MacBook Airs powered by Intel’s state-of-the-art Sandy Bridge Core “i” processors, and supporting the new high-speed Thunderbolt I/O port.last month in preparation for consumer launch as soon as OS X 10.7 Lion is released
