NAND Flash and the Future of Enterprise Storage Enabling Products Or Enabling Profits? NAND Flash and The Future of Enterprise Storage Enabling Products or Enabling Profits? He who foretells the future lies, even if he tells the truth. John Monroe —Arab Proverb Research Vice President Infinitely self-similar, Gartner Storage Group never the same… Joseph Unsworth Mobile Research Director Desktop Gartner Semiconductor Group IDEMA DISKCON Enterprise September 2008 Notes accompany this presentation.

WhereGart nerDo is aWe registered Come trademar From?k of Gartner What, Inc. or its are affiliates. We? Where Are We Going? Why SSDs in the Enterprise? • HDDs have made enormous advances in capacity, cost per GB and reliability but much more limited advances in performance. • With HDDs, enterprise IOPS per GB have actually declined. • There will be a growing need for “storage network accelerators” (SNAs) in a variety of enterprise applications. Key Issues 1. What are the key market trends and applications fueling data growth? This image can serve as a kind of metaphor for “seamless integration,” reflecting a coalescence of storage systems that can—with endless, scalable replication, simplicity and beauty—“solve” the problem of infinity at every edge. 2. What are the storage technologies and architectures that best address the complexity, cost and environmental challenges faced by IT professionals? 3. What are the current NAND flash industry dynamics? The Evolving Storage Landscape • The Internet has one key purpose: The quick transport of digital data in multiple forms to multiple locations. All other uses have evolved from that initial aim. • Increased storage at any point in the World Wide Web increases the possibilities for storage in every part of the Web. We are only beginning to see the enormous implications of that simple sentence.

  • Micron: NAND Flash Architecture and Specification Trends
    NAND Flash Architecture and Specification Trends Michael Abraham ([email protected]) Applications Engineering Manager Micron Technology, Inc. Santa Clara, CA USA August 2009 1 Abstract As NAND Flash continues to shrink, page sizes, block sizes, and ECC requirements are increasing while data retention, endurance, and performance are decreasing. These changes impact systems including random write performance and more. Learn how to prepare for these changes and counteract some of them through improved block management techniques and system design. This presentation also discusses some of the tradeoff myths – for example, the myth that you can directly trade ECC for endurance Santa Clara, CA USA August 2009 2 NAND Flash: Shrinking Faster Than Moore’s Law 200 100 Logic 80 DRAM on (nm) ii 60 NAND Resolut 40 Micron 32Gb NAND (34nm) 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 Semiconductor International, 1/1/2007 Santa Clara, CA USA August 2009 3 Memory Organization Trends Over time, NAND block size is increasing. • Larger page sizes increase sequential throughput. • More pages per block reduce die size. 4,194,304 1,048,576 262,144 65,536 16,384 4,096 1, 024 256 64 16 Block size (B) Data Bytes per Page Pages per Block Santa Clara, CA USA August 2009 4 Consumer-grade NAND Flash: Endurance and ECC Trends Process shrinks lead to less electrons ppgger floating gate.

For consumer applications, endurance becomes less important as density increases.

NAND has been the only commodity memory with no standard interface – Command set, timings, and pin-out are similar among vendors NAND has been ripe for standardization due to a few inflection points: – 1) Explosion in use of NAND for MP3 players, phones, caches, and SSDs – 2) Increase in number of NAND vendors serving the market (2 to 6+) ONFi Workgroup was formed in May 2006 to address “gap” – ONFI = Open NAND Flash Interface ONFi revision 1.0 delivered in December 2006, defines: – Uniform NAND electrical and protocol interface • Raw NAND component interface for embedded use • Includes timings, electrical, protocol • Standardized base command set – Uniform mechanism for device to report its capabilities to the host ONFI 1.0 sets a solid foundation for NAND (r)evolution. 4 A-Data Afa Technologies Alcor Micro Aleph One Anobit Tech.

In this lawsuit, at issue are six patents belonging to plaintiff: United States Patents Nos. 7,397,713 (‘713 patent); 7,492,660 (‘660 patent); 7,657,702 (‘702 patent); 7,532,511 (‘511 patent); 7,646,666 (‘666 patent); and 7,646,667 (‘667). These patents all share specifications with patents brought in two previous lawsuits, Cases Nos. 07-cv-605-bbc and 07-cv-607-bbc. Now before the court are defendants’ motion for summary judgment of noninfringement, plaintiff’s motion to strike portions of that motion and to strike portions of a rebuttal expert report, motions from both parties for leave to file additional briefing on the motion to strike, and defendants’ motion for leave to file corrected versions of expert reports. I will grant the motions for leave to file additional briefing but deny the motion to strike and grant the 1 motion to file corrected versions of expert reports. I will also grant defendants’ motion for summary judgment of noninfringement in full. As a result, it is not necessary to address the question of damages, and in my discretion I decline to exercise jurisdiction over the remaining invalidity claims and will thus deny the motion for summary judgment of invalidity.
