Flash fryers have burger problems: You can't keep adding layers

Backgrounder The flash foundry folk took on 3D NAND because it provided an escape hatch from the NAND scaling trap of ever-decreasing cell sizes eventually to non-functioning flash. But 3D NAND, the layering of many 2D planar NAND chip structures, will run into its own problems. These are to do with wafer production time and yield, and …

NAND that's that... Flash chip industry worth twice disk drive biz

Analysis The flash industry is worth more than twice the disk drive industry in terms of product ship revenues. Trends suggest a shrinking disk drive industry will squeeze the three drive manufacturers, leaving Seagate with no escape. Storage sector analyst Aaron Rakers has run supplier numbers through his spreadsheets and reckons the …

Samsung ploughing billions into boosting memory production

Memory and flash fabber Samsung is boosting production, convinced that high demand for chips is here to stay. Demand will stay high, Samsung says, because the Internet of Things (IoT), artificial intelligence (AI), big data and automotive technologies all need more DRAM and flash. It says it will invest KRW 30 trillion ($26. …

Japan mulls semi-nationalising Tosh (memory biz) – report

The Japanese government is considering providing state-backed aid to Toshiba’s memory business, amounting to near partial nationalisation, to prevent it falling into Chinese or South Korean hands, according to a report. The article in Nikkei Asian Review goes on to say that the Development Bank of Japan is considering a …

Foxconn 'very confident' of buying Toshiba's NAND business

Foxconn has confirmed speculation that it is one of the companies bidding for a slice of Toshiba's silicon business. The news came in a speech given by founder Terry Gou to mark the company breaking ground for a multi-billion-dollar display factory in the southern China province of Guangzhou. The factory will cost the company …

NAND, fab-ulous NAND, price rises make DRAM a cash cow

Happy days for Micron, it seems. Its first fiscal 2017 quarter results were lifted by high demand and price rises driven by supply constraints. The market wanted more DRAM and NAND bits than the firm's fabs could ship and DRAM prices went up. Revenues of $3.97bn were 18.5 per cent higher than a year ago and 23 per cent upon …

Flash reaches the enterprise tipping point

Comment The use of disk drives to store performance data for enterprises is declining and, flash drives - SSDs - are taking their place. A wave of all-flash array (AFA) to disk array migration is starting to wash across data centres as generations of disk drive arrays give way to ones built with NAND flash drives. The tipping …

QLC flash is tricky stuff to make and use, so here's a primer

QLC flash primer Quad-level cell (QLC) flash stores 4 bits per NAND cell and is very tricky stuff to use, far trickier than TLC (3 bits/cell) which is harder to user than 2 bits/cell MLC which, you guessed it, is more difficult to use than 1bit/cell SLC. Why is QLC the hardest of all to use? It is the slowest to read and write …

Flash is too fat. A glut of supply means growth is slower and slower

NAND flash industry revenue was $8.307bn in the fourth quarter of fiscal year 2015, five per cent less than a year ago and 2.3 per cent lower than in the third 2015 quarter. These numbers, evidence of market over-supply, come from DRAMeXchange via analyst outfit Stifel Nicolaus' MD, Aaron Rakers. Samsung grew its flash …

Don't want to fork out for NAND flash? You're not alone. Disk still rules

NAND flash shipments are not catching up with disk, casting doubt on the idea that disks will disappear from data centres, according to the latest research. Stifel MD Aaron Rakers used data from Samsung, Gartner and others to tabulate capacity-based shipment data for consumer and enterprise disk and flash storage devices. …

Data centre disk use is spinning down – Wikibon report

Decades of disk domination are coming to a close: Wikibon sees flash replacing disk entirely for primary data storage enterprise and hyper-scale cloud data centres over the next ten years. Disk will still be used as the cheapest and fastest – for the price – bulk-capacity media for archival and other low-access rate data. The …

Will flash save the data centre? Don't spread your wings yet, Vultan

Analysis The all-flash data centre: does it exist? Will it ever? Can we really imagine a data centre with no spinning disks and all the executing apps relying on solid-state storage? Such is the vision put forward by Violin Memory in its "Disk is Dead" campaign. But is this the future of the data centre? Violin chief marketeer Amy …
