The new 128GB embedded device integrates sixteen 64Gbit (equal to 8GB) NAND chips fabricated with Toshiba's 32nm process technology and a dedicated controller into a small package 17 x 22 x 1.4mm (planned to be standardized to JEDEC specification). Toshiba is the first company to succeed in combining sixteen 64Gbit NAND chips, and applied chip thinning and layering technologies to realize individual chips that are only 30 micrometers thick.
Toshiba offers a line-up of single-package embedded NAND Flash memories in densities from 2GB to 128GB. They integrate a controller to manage basic control functions for NAND applications, and are compatible with the JEDEC e-MMC Version 4.4 and its new features. New samples of 64GB chips will also be available from August.
- The JEDEC e-MMC V4.4 compliant interface handles essential functions, including writing block management, error correction and driver software. It simplifies system development, allowing manufacturers to minimize development costs and speed time to market for new and upgraded products.
- The 128GB device stacks sixteen 64Gbit chips fabricated with 32nm process technology. Application of advanced chip thinning, layering and wire bonding technologies has allowed Toshiba to achieve individual chips only 30 micrometers thick, and to layer and bond them in a small package. The result is an embedded flash memory module with the industry's highest density.
- The new products are sealed in a small FBGA package only 17 x 22 x 1.4mm and has a signal layout compliant with the JEDEC e-MMC V4.4.
