They are for applications in digital consumer products, including smartphones, mobile phones, netbooks and digital video cameras.
The 64Gbyte device combines 16 32Gbit (equal to 4Gbyte) NAND chips fabricated with 32nm process technology, and integrates a dedicated controller.
Applied chip thinning and layering technologies realise individual chips that are 30µm thick.
Compliance with the Jedec MMCA v4.4 standard for embedded multimedia cards supports standard interfacing and embedding in products. The v4.4 interface handles essential functions, including writing block management, error correction and driver software.
The integrated controller manages basic control functions for NAND applications, and is compatible with the latest E-MMC standard, including defining multiple storage areas and enhanced security features.
The device can record up to 1070 hours of music at a 128kbbit/s bit rate, 8.3 hours of full specification high definition video and 19.2 hours of standard definition video (HD and SD are calculated at average bit rates of 17 and 7Mbit/s, respectively).
The product is sealed in an FBGA package measuring 14 by 18 by 1.4mm.
