Toshiba commercializes Industry's Highest Capacity Embedded NAND Flash Memory for Mobile Consumer Products

17 April, 2007

Achieves 16G capacity and also integrates controller function

TOKYO---Toshiba today announced that the company has commercialized a new series of embedded NAND Flash memory devices which is compliant to eMMCTM*1 , that achieve the industry's largest capacity. The new 16 gigabyte (GB) devices are designed for application in mobile consumer products, such as mobile phones and video cameras. Samples will be available in the second quarter of this year and mass production will start in the forth quarter. Ahead of that, Toshiba will start shipping 8GB samples from this month, and start mass production in the third quarter.

The new 16GB chip combines eight 2GB NAND chips fabricated with Toshiba's cutting-edge 56nm process technology, along with a controller chip, in a standard small size package. The new embedded memory offers advantages that realize a versatile, easily applied solution: the largest capacity yet achieved in this product category will bring new capabilities to mobile consumer products; integration of a dedicated controller reduces product development burdens on product manufacturers; and full compliance with the MMCA Ver. 4.2 high speed memory standard for memory cards, as defined by the MultiMediaCard Association, supports standard interfacing and simplified embedding in products.

Toshiba will launch a series of embedded NAND Flash memories based on the new technology, ranging from 1GB to 16GB in capacity. This wide line-up of eMMCTM compliant products, will allow the new devices application in a wide range of products.

There is growing demand for memories with a controller function that minimizes development requirements and eases integration into system designs. Toshiba has responded with products such as the LBA-NANDTM*2 memory, which incorporates basic control function for NAND application, and GB-NANDTM*2, a large capacity chip with SD interface. Adding the eMMCTM compliant line-up to its portfolio will assure Toshiba's continued leadership in this expanding market.
