In June 2010 -
Macronix
announced
research results related to its patented BE SONOS (barrier engineering)
charge-trapping technology which could make terabit NAND flash feasible.
Using 3D stacking, NAND Flash may achieve higher data storage capacity
and effectively lower fabrication cost without relying on advances in
lithography technology. Therefore, some memory manufacturers have invested in 3D
research recently.
In December
2012 - Macronix
described an experimental design of flash cells with on-chip annealing super
heaters - which the company said could be used to refresh endurance to over
100 million cycles. |

eliminates flash endurance limit |
Editor:- December 2, 2012 -
An article in IEEE Spectrum -
Flash
Memory Survives 100 Million Cycles - summarizes a recent research paper by
Macronix -
which described an experimental technique to redesign flash cells to improve
endurance.
The
technique - which StorageSearch.com does not think is feasible to scale for
commercially competitive memory densities - involves designing addressable
heaters in the memory array which can pulse upto 800 degrees C for a few
milliseconds. This thermal "refreshing cycle" anneals the chip
material and heals common wear-out defects while also enabling the cells to be
run faster.
“Afterward, we realized that there was no new physics
principle invented here, and we could have done this 10 years ago” said
Hang-Ting Lue,
the project director at Macronix | | |

| Surviving SSD
sudden power loss |
Why should you care
what happens in an SSD when the power goes down?
This important design
feature - which barely rates a mention in most SSD datasheets and press releases
- has a strong impact on
SSD data integrity
and operational
reliability.
This article will help you understand why some
SSDs which (work perfectly well in one type of application) might fail in
others... even when the changes in the operational environment appear to be
negligible. |
