Micron Makes ClearNAND Embedded ECC Flash

By - Source: Tom's Hardware US | B 9 comments

Better flash for better speeds.

Micron Technology today introduced a new flash memory technology that integrates the error management techniques inside the NAND package, calling it ClearNAND.  The technology is applicable for products ranging from enterprise servers to consumer devices such as tablets and portable media players.

ClearNAND products utilize a traditional raw NAND interface, and include new features that are optimized for high-capacity and high-performance applications, said Micron. Furthermore, ClearNAND products are first designed using its 25nm multi-level cell (MLC) process, and are available in two versions: Standard and Enhanced.

Micron's Standard ClearNAND products come in 8 to 32 GB packages, while the Enhanced variants come in 16 to 64GB, and are intended to remove the ECC burden from the host processor with minimal protocol changes compared to raw NAND. This potentially means that controllers can divert more resources into making things even faster.

    Faster is always nice but I think at this point more people care about cheaper.....

    How about some throughput tests with ECC on and off. Then compared to other SSD's with ECC on and off....

    You did read the article right? This is a chip product not an SSD. It will find it's way into SSD devices soon I'm sure. Then you can get your benchmarks.

    sounds awesome...
    How about making it cheaper than it is now? 2USD/Gb is practically wallet rape.

    Nice more efficient intelligent NAND.

    Should start seeing products using this by Jun 2011.

    This is more like it than speed - reliability.

    I bet people thought the same when standard HDDs were that much. Well then again we didn't have anything that was older tech with larger storage capacities and didn't need it as much.

    Its not that bad. If we look at a timeline of HDDs from when they hit and compare their $/GB drop compared to SSDs then I think we would see that SSDs dropped much faster than HDDs did.

    Much like DDR2 go cheaper faster than DDR and DDR3 got cheaper faster than even DDR2.

    I heard the 25nm flash memory seems to be suffering from a seriously reduced lifetime, and increased errors due to it's so tiny design...!
