    Samsung has developed the world's first 64 Gigabit (Gb) multi level cell (MLC) NAND flash memory chip -- using 30-nanometer (nm)-class process technology. The flash memory device represents a major leap forward in the move to higher density flash storage solutions at a time of exploding demand for flash as the main storage medium in computing and other digital applications.


    The new flash device was successfully developed through the use of a new manufacturing process called self-aligned double patterning technology (SaDPT). In SaDPT, the 1st pattern transfer is a wider-spaced circuit design of the target process technology, while the 2nd pattern transfer fills in the spaced area with a more closely designed pattern. (Refer to image)

    SaDPT represents a pivotal advancement beyond the charge trap flash (CTF) technology that Samsung developed for NAND flash last year when it introduced a new material (silicon nitride) and a new structural configuration. SaDPT resolves a critical bottleneck to forming sub-30nm circuitry by expanding the role that conventional lithography technology plays in the manufacturing process. Both Samsung's CTF-based NAND flash technology and SaDPT are expected to provide improvements in cost efficiency for next-generation nanometer-scale designs.

    Samsung's SaDPT will employ existing photolithography equipment in 30nm-class production, which is expected to be commercialized beginning in 2009. By utilizing conventional photolithography equipment, Samsung can not only significantly speed up the process but also improve the cost efficiency of its manufacturing operations without additional facility investment. Samsung has applied for 30 patents in connection with its new 64Gb flash device.

    Samsung also has developed a 32Gb single level cell (SLC) NAND flash chip based on the same technology applied to its 64Gb chip. Samsung's continued success in introducing higher density NAND flash will intensify demand for solid state drives in notebooks, and for other NAND-based storage devices in applications such as digital camcorders and enterprise servers.

    Samsung expects to begin production of 30nm-class 64Gb flash devices in 2009. According to Gartner Dataquest, the accumulated sales for 64Gb NAND flash and higher density devices could reach up to $20 billion in just three years (2009-2011).

    I like flash, and I really like flash in notebooks or SSD's. Bigger capacities and reduced manu. costs mean we will see more of this in the future.

    I'm sure we'll see flash OS partitions within the next 18months for fast boot up times, and lag free desktop use. All we need is a FAST IDE or SATA compatible 8GB partition at a good price, and I'm sure EVERYONE on this forum would implement it.

    I'm still waiting to see SSD's come down to a sensible price in a 2.5" format. My laptop is begging for a new drive. They also make a nice performance upgrade. The extra ZOOM is like having a new system. It also makes the ultralowpower portables much more useable. Their slower clocked CPUs arent so noticeably a drag if the HDD is SSD and therefore the memory substructure is performing better.

    Now if they translate this into their other products, we would be in a better position. Good going Samsung.
