Toshiba And SanDisk Launch 3D Flash Chip

Toshiba has announced the world’s first 48-layer Bit Cost Scalable (BiCS) flash memory chip.

The BiCS is a two-bit-per-cell, 128Gb (16GB) device with a 3D-stacked cell structure flash that improves density and significantly reduces the overall size of the chip.

Toshiba is already using 15nm dies so, despite the layering, the finished product will be competitively thin.

24 hours after the first announcement, SanDisk made one of its own regarding the announcement. The two companies share a fabrication plant and usually make such announcements in close succession.

“We are very pleased to announce our second-generation 3D NAND, which is a 48-layer architecture developed with our partner Toshiba,” said Dr Siva Sivaram, executive vice president of memory technology at SanDisk.

“We used our first generation 3D NAND technology as a learning vehicle, enabling us to develop our commercial second-generation 3D NAND, which we believe will deliver compelling storage solutions for our customers.”

Samsung has been working on its own 3D stacked memory for some time and has released a number of iterations. Production began last May, following a 10-year research cycle.

Moving away from the more traditional design process, the BiCS uses a ‘charge trap’ which stops electrons leaking between layers, improving the reliability of the product.

The chips are aimed primarily at the solid state drive market, as the 48-layer stacking process is said to enhance reliability, write speed and read/write endurance. However, the BiCS is said to be adaptable to a number of other uses.

All storage manufacturers are facing a move to 3D because, unless you want your flash drives very long and flat, real estate on chips is getting more expensive per square inch than a bedsit in Soho.

Micron has been talking in terms of 3D NAND since an interview with The INQUIRER in 2013 and, after signing a deal with Intel, has predicted 10TB in a 2mm chip by the end of this year.

Production of the chips will roll out initially from Fab 5 before moving in early 2016 to Fab 2 at the firm’s Yokkaichi Operations plant.

This is in stark contrast to Intel, which mothballed its Fab 42 chip fabrication plant in Chandler, Arizona before it even opened, as the semiconductors for computers it was due to produce have fallen in demand by such a degree.

The Toshiba and Sandisk BiCS chips are available for sampling from today.

SanDisk Debuts Wireless Flash Drive

SanDisk on Monday announced a line of wireless flash drives that can hold up to 64GB of data.

The new drives include the Connect Wireless Flash Drive — a thumb drive — and the Connect Wireless Media Drive, a larger, but still pocket-sized storage device. The Connect Wireless Flash Drive comes in 16GB and 32GB capacities; the Connect Wireless Media Drive comes in 32GB and 64GB capacities.

The Connect Wireless Flash drive is 3.07-in. x 1.04-in. x 0.54-in. The Connect Wireless Media Drive is 2.6-in. x 2.6-in. x 0.52-in.

The Connect Wireless drive family allows users to not only store but share and stream files across multiple mobile devices. They offer up to eight simultaneous device connections and three media streams, and support separate streams of 720p video content at 2MB/sec to three or five devices concurrently (for the Flash Drive and Media Drive, respectively).

According to a SanDisk spokesman, video streaming performance isn’t affected by multiple streams because device limits are set at a point that supports the streams without degradation. Devices can connect to the drives up to 150 feet away.

The Connect Wireless drives work with all iOS and Android devices, and Kindle Fire tablets, as well as PC and Mac computers. The drives are compatible with Windows 8, Windows 7, Windows Vista, Windows XP and Mac OS 10.6 or higher

Movies, music, photos and documents can be loaded onto the wireless drives by simply dragging and dropping the files, which can then be accessed via the SanDisk Connect apps. Those apps are available for download from the App Store, Google Play Store and the Amazon Appstore for Android.

The drives contain an internal router, so no external router or Internet connection is needed to stream media. In order to use the drives, mobile device users simply download SanDisk’s Connect App.

The drives run on lithium-ion batteries. A single charge provides up to four hours of wireless streaming, with streaming data protected by Wi-Fi Password Protection (WPA2).

“With the new SanDisk Connect product line, we’re raising the bar on what consumers can expect from personal storage,” said Dinesh Bahal, vice president for product marketing for SanDisk.

The SanDisk Connect Wireless Flash Drive is available in 16GB or 32GB capacities for $49.99 and $59.99, respectively. In the U.S., it is available for preorder on Amazon.com, Newegg.com and Micro Center, with availability at Best Buy starting in August. It will also be available for preorder on Amazon.com in Germany and UK.

The SanDisk Connect Wireless Media Drive has a retail price of $79.99 for 32GB or $99.99 for 64GB storage capacity. It is available for preorder in the U.S. on Amazon.com, with availability in Germany and UK in the fourth quarter of 2013.
