Samsung starts production of first 20nm NAND flash memory chips for SD cards
By David Gonzales on 19 Apr 10Samsung has beat every other memory chip maker to the punch as it has just begun production of the industry’s first 20 nanometer-class NAND flash chips for use in Secure Digital (SD) memory cards and embedded memory solutions. And the great thing about it is, the smaller size actually translated into better performance, as Samsung explains:
Samsung has made available the next generation node 20nm-class NAND, which exceeds most customers requirements for high-performance, high-density NAND-based solutions. The new 20nm-class NAND is not only a significant step forward in process design, but we have incorporated advanced technologies into it to enable substantial performance innovation.
For those who like to deal with the specifics, Samsung says that the new 20nm-class NAND chips perform 30% faster (in terms of write speed) than their 30nm-class counterparts. These also offer a speed-class rating of 10 (read speed of 20MB/s, write speed of 10MB/s).
Samsung is already shipping card samples using this new design process to its memory chip customers, and we consumers should be able to take advantage of the new cards in 4GB to 64GB variants later this year.
