Fat NAND controllers to slim down

Micron says some flash controller jobs are going to migrate down stack towards the NAND chips, freeing up controller manufacturers from chip-dependent work they shouldn't be doing. It sees low-level flash controllers developing and taking on error management, taking this job away from existing NAND controllers. Micron takes the …

Flash breaks free from the storage flat earth society

NAND used to be the sole prerogative of a two-dimensional flat earth society obsessed with shrinkage, but that approach is running into a technological dead end. To get more capacity the only feasible escape is upwards, using the third dimension and stacking layers of 2D flash to build multi-layered chips. The dead end is …

A day may come when flash memory is USELESS. But today is not that day

The era of flash memory is anticipated to run out of road in the 2020s and newer technologies involving resistance and electron spin are poised to take over, delivering higher capacities, greater speed and DRAM-style addressability. Some people ask if one of these new technologies could actually unify dynamic memory (RAM) and …
