HLNAND SSD Achieves Unprecedented Per-channel Flash Performance

HLNAND SSD Achieves Unprecedented Per-channel Flash Performance

 

MOSAID Technologies Inc. today introduced a Solid State Drive (SSD) prototype utilizing MOSAID's innovative HyperLink NAND (HLNAND) architecture and interface. Designed by MOSAID and its development partner INDILINX, the HLNAND SSD prototype is optimized for mass storage applications, including enterprise data centers and high-performance computing environments.

 

MOSAID's HLNAND SSD prototype proves that 213MBps read performance and 130MBps write performance is achievable on a single channel of HLNAND Flash memory. In contrast, current second-generation SSDs require eight or more channels for the same level of performance.

"The goal of the HLNAND program is to develop advanced solutions that will significantly enhance the performance of Flash technology in commercial products," said Jin-Ki Kim, Vice President R&D, MOSAID. "Our prototype demonstrates the unprecedented level of Flash performance and flexibility that can be delivered in an SSD when implementing HLNAND technology. With our solution, SSD designers can achieve an industry leading concentration of throughput on each channel, without experiencing roll-off with heavily populated rings."

 

As the first major new Flash memory architecture and device interface development in 20 years, HLNAND Flash combines MOSAID's HyperLink memory technology with industry standard NAND Flash cell technology. HLNAND delivers sustained input/output (I/O) bandwidths an order of magnitude higher than conventional Flash by utilizing a point-to-point ring topology that achieves an extremely high level of signal integrity and significantly reduced loading.

HLNAND SSD Prototype - Design Details

 

The HLNAND SSD is a fully functional, Serial ATA 3 Gbps (SATA II) compatible prototype incorporating a Field Programmable Gate Array (FPGA)-based controller and MOSAID's HLNAND modules, built in the 3.5 inch form factor. The HLNAND SSD prototype uses two 64GB HLDIMM modules (eight multi-chip packages (MCPs) per module, 16 MCPs in total) arranged on a single channel. MOSAID provided the HLDIMM modules, and INDILINX built the controller and system board.

 

Prototype design limitations required reducing the HyperLink channel clock from 133 MHz to 75 MHz. A production version of the HLNAND SSD utilizing an FPGA-based or ASIC-based controller with eight channels would operate at the full 133 MHz clock to achieve read and write throughput each exceeding 1 TB/s.

 

The HLNAND SSD is intended for use in high-speed, mass storage applications, including desktop workstations, computing and enterprise equipment, light-weight mobile devices and gaming equipment, or as external drive.

 

Availability

 

Licenses for manufacturing MOSAID's HLNAND 64Gb NAND Flash memory device and 64GB HLDIMM module in production quantities are available to semiconductor suppliers, packaging and module suppliers, product manufacturers and system integrators. MOSAID's engineering team is ready to support licensees for rapid product introduction.
