MOSAID Technologies Inc. has announced its HLNAND™2 memory interface for flash memory SSDs, which is optimized for use in mass storage applications, including enterprise data centers and high-performance computing.
MOSAID's HLNAND (HyperLink NAND) Flash Memory Specification 2 uses a high-speed, point-to-point ring topology, enabling SSD data transfer rates into the multiple Gigabyte-per-second range. With a raw data rate of up to 800MB/s per channel, and 1600MB/s per channel with DuplexRW™, HLNAND2 requires only one memory channel to reach a data transfer rate on the host interface exceeding 1 GB/s.
8-bit, synchronous, DDR data bus
operates at up to 400MHz to deliver up to 800MB/s of throughput Flash interface speed closely matched to high-speed system interconnects such as PCIe generations 2 and 3
DuplexRW™: Simultaneous DDR800 read & write, effectively 1600MB/s data throughput
Power saving by automatic packet truncation
Built-in EDC (Error Detection Code)
Engineering samples will be available later in 2011
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
