Toshiba Corp has introduced the 32GB embedded NAND Flash memory modules that offer what is claimed to be the largest density yet announced plus full compliance with the e-MMC and eSD standards. The embedded devices are targeted at application in mobile digital consumer products, including mobile phones and video cameras.
The 32GB embedded devices combine eight 32-Gbit (4GB) NAND chips fabricated with the company's 43nm process technology and also integrate a dedicated controller. Full compliance with JEDEC/MMCA Ver 4.3 and SDA Ver 2.0, high-speed memory standards for memory cards as defined by the MultiMediaCard Association and SD Card Association, respectively, supports standard interfacing and simplified embedding in products, reducing development burdens on product manufacturers.
The company offers a line-up of single-package embedded NAND Flash memories which include a controller to manage basic control functions for NAND applications: LBA-NAND memory, which has a NAND interface; eSD large capacity chips with SD interface; and e-MMC with an HS-MMC interface. Available in densities ranging from 1GB to 32GB, this line-up supports application in a wide range of products. The devices can record up to 560 hours of music at a 128Kbps bit rate, 4 hours of full spec HD video and 7.3 hours of SD video.
Samples of the 32GB embedded NAND Flash memory devices will be available in September this year, while mass production will start in Q4.
