New research: Flash is DEAD. Yet resistance isn't futile - it's key

Flash is at a crossroads. It cannot keep shrinking dies because, beyond a certain point, NAND cells produce too many errors, are slower to respond and have a shortened working life. Yet a University of Michigan professor's research may hold the key to the future of flash storage technology. Flash foundry suppliers are working on …

Micron: Hot DRAM. We don't need no steenkin' PCM

Micron has reportedly withdrawn Phase Change Memory (PCM) products from its portfolio. Electronics360 says Micron has removed “128-Mbit 90nm serial and parallel NOR pin-out PCM devices from the products listed on its website". Sure enough we couldn’t find them there.

HGST polishes Ultrastar SSD whoppers, stuffs with denser Intel flash

HGST has refreshed its Ultrastar enterprise SSD line, using denser 20nm NAND to replace the previous 25nm flash, doubling capacity, upping read performance but lowering write performance a tad in the process. The starting point was a three-product Ultrastar SSD800 line-up, maxing out at 800GB and coming in MH (write-intensive), …

Resistance is not futile: Here's a cookie sheet of luke-warm RRAM that proves it

Boffins devising Resistive RAM (RRAM) have found that using porous silicon oxide makes the devices easier to manufacture, longer lasting and less power hungry. The researchers, at Rice University, Texas, stumbled upon silicon oxide RRAM five years ago. The stuff works as computer storage by having differing resistance levels …

Shocking new low for SanDisk – 15nm flash chips rolling out its fabs

SanDisk has powered up the smallest NAND process in the industry, 15nm, meaning it should be able to get more working flash chips from each silicon wafer – and thus lower its costs. It's calling this technology "1Z", as 1X is below 20nm, and 1Y is between that and 15nm. These alphabetic suffix boundaries are not standard, and …
