    MOSAID Technologies Inc. today announced that it is sampling the industry's first NAND Flash MCP (multi-chip package) with a 16-die NAND stack operating on a single high-performance channel.

    MOSAID's 512Gb HLNAND (HyperLink NAND) MCP combines a stack of 16 industry standard 32Gb NAND Flash die with two HLNAND interface devices to achieve 333MB/s output over a single byte-wide HLNAND interface channel. Conventional NAND Flash MCP designs cannot stack more than four NAND dies without suffering from performance degradation, and would require two or more channels to deliver similar throughput.

    “The 16-die stack 512Gb HLNAND MCP demonstrates the superior scalability of HLNAND‘s ring architecture compared to the parallel bus architecture used in industry standard NAND Flash products,” said Jin-Ki Kim, Vice President of R&D, MOSAID. “HLNAND’s ring architecture allows a virtually unlimited number of NAND die to be connected on a single channel without performance degradation.”

    “HLNAND confers distinct performance and form factor advantages,” said Peter Gillingham, Vice President and Chief Technology Officer, MOSAID. “Using HLNAND technology, system engineers can design Gigabyte per second bandwidth and Terabyte capacity Solid State Drives (SSDs) with a single controller chip. Competing designs utilizing industry standard NAND MCPs will require multiple controller chips.”

    Features of the 16-die stack 512Gb HLNAND MCP:
    • 2 HLNAND interface die and 16 32Gb NAND die
    • I/O data rate: 333MB/s (DDR333) at 1.8V
    • Low power operation - no termination resistors required
    • Simultaneous read and write data transactions at full data rate for 667 MB/s aggregate data throughput
    • Fully independent LUN (logical unit number) operation
    • Package: 100-ball BGA (ball grid array) measuring 18mm x 14mm
    HLNAND Flash is a high-performance solution that combines MOSAID‘s own HyperLink memory technology with industry standard NAND Flash cell technology to deliver the industry’s most advanced feature set, reaching sustained I/O input-output bandwidths more than ten times higher than conventional Flash.

    so will this also lower costs?

    A 128GB drive could be made with just two of these chips... so the answer tends to be yes.

    This sounds like it could be a major kickstart to wide stream SSD production at lower costs.
    Less parts and good bang for the buck.
    Also, ability to mass produce much larger capacity SSDs.
    Native speeds would help push further developments in the need for speed race.

    I look forward to cube shaped BGA packaging for NAND flash.

    As for someone like myself with limited knowledge of SSD production.

    How long till we see this tech in SSDs? How much will this effect cost per gb?

    It's difficult to say. You'd need a big flash company to manufacture them, and a big SSD vendor to market them. ToggleNAND got its big break because it was well connected (marketed by Samsung). HLNAND appears to be more for small SSDs (embedded onto logic boards, and mSATA).
