WD announces 96-layer 3D NAND, initial production output in 2018


NAND isn’t the nickname of your grandmother, but the technology in the storage chips inside your smartphones, tablets and computers, with Western Digital announcing an industry first.

It was just on two weeks ago that Samsung announced its 4th-generation, 64-layer V-NAND technology was now in “full production”, and its own moves toward the terabit V-NAND era, with 90-layer technology.

Samsung said its move to full production delivers productivity and reliability gains, greater energy efficiency, and more storage for ever hungrier users demanding greater storage capacities at the same or better prices.

Now comes its competitor, Western Digital (WD), announcing it has “successfully developed its next-generation 3D NAND technology, BiCS4, with 96 layers of vertical storage capability.”

The announcement doesn’t mean full production as yet, however, with WD stating “sampling to OEM customers is expected to commence in the second half of calendar year 2017 and initial production output is expected in calendar year 2018".

WD notes its BiCS4 technology was developed jointly with manufacturing partner Toshiba Corporation, and “will be initially deployed in a 256-gigabit chip and will subsequently ship in a range of capacities, including a terabit on a single chip.”

Clearly, it is fantastic to see this solid competition between Samsung, WD, Toshiba and everyone else in this game, because traditional slow hard drives need to be eliminated from consumer products, and devices such as the new iPad Pro models with up to 512GB of storage (and larger in the future!) need to start becoming standard capacities for consumers and business users sooner rather than later.

Dr. Siva Sivaram, executive vice-president of Memory Technology at Western Digital, naturally had something to say about his company’s development, stating: “Our successful development of the industry’s first 96-layer 3D NAND technology demonstrates Western Digital’s continued leadership in NAND flash and solid execution to our technology roadmap.

“BiCS4 will be available in 3-bits-per-cell and 4-bits-per-cell architectures, and it contains technology and manufacturing innovations to provide the highest 3D NAND storage capacity, performance and reliability at an attractive cost for our customers.

“Western Digital’s 3D NAND portfolio is designed to address the full range of end markets spanning consumer, mobile, computing and data centre.”

WD also proudly boasted of its “strong ongoing operations at its joint venture manufacturing facilities in Japan".

In particular, the company “reiterated its expectation that in calendar year 2017, the output mix of its 64-layer 3D NAND technology, BiCS3, will comprise more than 75% of its overall 3D NAND bit supply".

WD says it “now believes that, along with its partner Toshiba Corporation, the combined 64-layer 3D NAND bit output of the joint ventures in calendar year 2017 will be higher than any other industry supplier in calendar year 2017.”

So, game on from WD to Samsung, but hey! Great news for us all. Keep it up, fellas — I want my 1TB iPhone — and I want my 10TB and larger iPhones after that!

WEBINAR event: IT Alerting Best Practices 27 MAY 2PM AEST

LogicMonitor, the cloud-based IT infrastructure monitoring and intelligence platform, is hosting an online event at 2PM on May 27th aimed at educating IT administrators, managers and leaders about IT and network alerts.

This free webinar will share best practices for setting network alerts, negating alert fatigue, optimising an alerting strategy and proactive monitoring.

The event will start at 2pm AEST. Topics will include:

- Setting alert routing and thresholds

- Avoiding alert and email overload

- Learning from missed alerts

- Managing downtime effectively

The webinar will run for approximately one hour. Recordings will be made available to anyone who registers but cannot make the live event.



Security requirements such as confidentiality, integrity and authentication have become mandatory in most industries.

Data encryption methods previously used only by military and intelligence services have become common practice in all data transfer networks across all platforms, in all industries where information is sensitive and vital (financial and government institutions, critical infrastructure, data centres, and service providers).

Get the full details on Layer-1 encryption solutions straight from PacketLight’s optical networks experts.

This white paper titled, “When 1% of the Light Equals 100% of the Information” is a must read for anyone within the fiber optics, cybersecurity or related industry sectors.
