China's interest in PCRAM is not strong. Its interest in RRAM is much stronger.

Since Microchip's Sanghi is interested in this technology and new products, there will be specific market requirement for PCRAM.

Some companies have NOR flash roadmap below 65 nm. At least to 4X nm. Beyond that is uncertainty for sure.

Microchip/SST split gate flash cell may don't have road map below 65nm.They may think something diffrent. That is the reason. They may has some sigma data to show the performance, but it really high risk to put in into MCU even their low end PIC market.

@JackT Thanks or the insight and the URL @vincentxia Some would argue it was ever thus within research groups; in the commercial world as well as in academia; in the west as well as in the east.

I worked in SIMIT before, known every single detail about it. the purpose of this research is not for mass production, but just getting funding from the gov.

China Gov: Funding SIMIT: Material/Phyics SMIC: Fab manufactory/Process Intergration Microchip SST: TD/Process/Device/Design/Product/Test/Marketing SST was acquired by microchip last year See the link: http://english.sim.cas.cn/ns/icn/200910/t20091019_45466.html Volume production? Is it NOR compatible product? Interesting and waiting for their risk production anoucement.How can they do something better than Micron.

@resistion I also suspect that SIMIT is using chalcogenide mixes and the assertion that the development is entirely proprietary is a legal position. If the development is ever commercially successful one might expect some patent horse trading or legal action, eventually.

@ubm112211 Perhaps you are referring to Shandong Sino-chip Semiconductors Ltd.? But as to the power which buried Qimonda; you will need to be more specific, without being libelous.

I think Chinese Academy of Sciences used chalcogenides like Ovonyx, based on the SIMIT papers I found. If these materials melt more easily than other semiconductor industry materials, their structure cannot be that stable..
