Google's self-driving cars involved in 11 crashes Google comes clean on the number of accidents its driverless cars have been in over the past six years. If you're wondering why you've never heard of NOR flash, here's one reason: NAND flash is a $40B industry; NOR flash is a $2B niche. It also costs significantly more than NAND, so if designers can replace NOR with NAND, they do. But there is a steady and growing market for NOR. NOR's big advantage is that it is a lot more rugged than NAND.
Every digital computing system requires non-volatile memory to retain the primary or necessary programs and data, permanently, in order to avoid data loss on occasions of power failure or system shutdown. This has led to the invention of non-volatile memories. NOR flash is a type of nonvolatile semiconductor memory widely used in electronic devices. The NOR flash memory was first introduced by Intel in 1988. In NOR flash memory, the individual memory cells are connected in parallel configuration, which enables fast random access to the content stored on the memory cells.
TORONTO – Jedec's new xSPI standard for non-volatile memory (NVM) devices is aimed meeting the demands of instant-on applications while also maintaining performance standards for NOR flash sitting outside of the SoC. Adesto Technologies, known for its small, ultra-low power NVM products, is claiming to be first out the gate, having been working on products and collaborating on the standard for the past three years. In a telephone interview with EE Times, Adesto Chief Techology Officer Gideon Intrater said its eXecute-in-Place (XiP) EcoXiP product family takes advantage of the new Jedec standards to give customers such as system developers and controller designers assured compatibility with controllers and peripheral devices that should accelerate adoption. Developed by a task force comprised of representatives from most NOR flash device manufacturers and several PC and microcontroller companies, the xSPI standard establishes mechanical, electrical and transactional guidelines for developing high-throughput octal devices. Although Jedec has been a defining organization for NAND flash, said Intrater, until recently NOR flash has been somewhat of a "wild west" in terms of standards, which has led to divergent products for enabling communications between host controllers and memories and confusion for controller designers.
Apple, a company that has led the laptop industry in its use of PCIe solid-state drives (SSDs), again upped the ante in performance with its latest refresh of the MacBook Pro, which may be the highest performing stock system on the market. The early 2015 refresh of the MacBook Pro sported an M.2 (gumstick) form factor, PCIe SSD that boasted peak sequential read speeds of 1.6GBps and max sequential write speeds of 1.5GBps. Computerworld's own benchmark tests with Blackmagic software on a 2015 13-in. MacBook Pro with Retina display revealed it could pin the needle at more than 1.4Gbps for writes and more than 1.3Gbps for reads. The new MacBook Pro's specs smoke its predecessor.
I attended the 7th Annual Non-Volatile Memories Workshop 2016 at UC San Diego this month. Frank T. Hady, Intel Fellow and Chief Architect of 3D XPoint Storage, gave a keynote address to a room full of PhDs and competitors. Of course, Intel was not ready to answer a number of vital questions, but what they did offer was illuminating. How to plan, manage, and optimize enterprise storage to keep up with the data deluge. First gen XPoint will be built on a 20nm process, and can be used both as storage and as system memory.
