  • editor's comments:- February 2012 - Macronix - entered the SLC nand flash memories market with 2 products aimed at embedded applications - 512Mb and 1Gb in 48-TSOP and 63-VFBGA packages.
selected Macronix milestones - from SSD Market History.

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.

experimental technique 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 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.
