Isn't it amazing how flash memory has grown over the years? Not too dissimilar from your ego, right? Just two years ago SanDisk was only offering 16GB modules in the high end of its iNAND embedded flash range, and today the same company presented a new MLC NAND chip with four times the capacity. The trick in this 64GB 32nm silicon gem is the same-old X3 flash technology (along with undisclosed, but evidently significant, "innovations in flash management"), which allows each cell to store three bits. Go on, OEMs -- just shove one of these chips into our next phone and we'll promise to leave you alone until next February. Wait, did we say "promise?" Try... we meant try.

SanDisk Doubles Storage Capacity for Mobile Phones and Portable Devices with Introduction of 64GB iNAND Embedded Flash Drives

* Support for e.MMC 4.4 Interface Now Available
* INAND EFDs Perform Boot, System Code and Mass Storage Functions With Single Device
* SanDisk's Advanced 32nm 3-bit-per-cell (X3) NAND Flash Technology Reduces Complexity of High Capacity Embedded Solutions


Mobile World Congress 2010

BARCELONA, Spain--(BUSINESS WIRE)--SanDisk Corporation (NASDAQ:SNDK), the global leader in flash memory cards, today introduced the new SanDisk® iNAND™ Embedded Flash Drives (EFD) with support for the e.MMC 4.4 specification. Based on 3-bit-per-cell (X3) NAND flash technology, the drives offer up to 64 gigabytes (GB)1 of capacity in a single device, and can be used for boot, system code and mass storage functions.

"The maturity of SanDisk's X3 flash technology together with innovations in flash management are what allow us to continue making higher embedded storage capacities, such as 64GB, a practical solution in the market"

An increasing number of mobile phones offer a wide array of applications and storage-intensive content such as movie and music playback, imaging capabilities, gaming, GPS map data, business applications and more. SanDisk iNAND EFDs are specifically designed for these advanced smartphones and provide high capacity and reliable storage in a power-efficient package with a small footprint.

SanDisk's X3 Technology Enables High Capacity Embedded Storage

SanDisk's advanced X3 technology enables the development of high capacity embedded solutions that are robust and power-efficient with minimal package complexity. The successful development and wide distribution of many X3-based products through OEM and retail channels in recent years demonstrates both the technology's maturity and SanDisk's ability to bring to market reliable yet innovative solutions.

SanDisk's memory management expertise and X3 controller technology allow for the continued cost-effective growth of mobile storage solutions. 64GB iNAND EFDs meet the reliability and performance requirements of OEMs for mobile system grade storage. The new 64GB iNAND EFD is based on an eight flash die stack design using SanDisk's advanced X3 32nm flash, and is offered in a 16x20x1.4mm form factor with a standard ball grid array (BGA) for quick integration into smartphone designs.

"The maturity of SanDisk's X3 flash technology together with innovations in flash management are what allow us to continue making higher embedded storage capacities, such as 64GB, a practical solution in the market," said Oded Sagee, director, mobile product marketing, SanDisk. "We understand the highly competitive environment in which our customers operate. By leveraging the substantial experience gained with our X3 NAND and significant advancements made in flash management technology, we offer our customers a very high return on their investment."

Optimized For Maximum Efficiency

SanDisk iNAND EFDs consolidate system code and user storage into a single embedded device in order to conserve precious board space, simplify smartphone design, reduce power consumption and save OEMs the cost of an otherwise needed separate boot device. In addition, the drives utilize a unique state-aware architecture that grants the mobile host additional degrees of control over the storage device, enabling optimal resource utilization and improved system responsiveness.

iNAND devices based on X3 technology fully comply with the e.MMC 4.4 specification and range in capacities from 4GB to 64GB.
