Link A Media Devices unveil a new 6 Gb/s SSD Controller

Ryan Martin / 12 years ago

Link_A_Media Devices (LAMD)today unveiled its flagship high-performance LM87800 SATA 6G SSD controller with proprietary eBoost technology. The highly-integrated device brings enterprise-class performance and endurance enhancement to the rapidly growing client SSD market.Designed to deliver superior performance, the architecture deploys extensive hardware acceleration, dedicated host-side and NAND-side ARM microcontrollers and a 6 Gb/s SATA host interface, enabling the LM87800 to deliver industry-leading performance of 90K sustained random read/write IOPS and 550 MB/s sustained sequential read/write throughput. The LM87800 is fabricated on a low-power and low-leakage process technology and employs sophisticated power management techniques to achieve ultra-low power consumption.

The LM87800 features highly robust data recovery capability based on Link_A_Media Device’s eBoost technology. eBoost significantly enhances the endurance of current and future generation NAND flash to bring enterprise-class reliability and lifetime to client SSDs while maintaining superior performance throughout the life of the SSD. eBoost achieves these key system objectives through the use of proprietary adaptive signal estimation techniques coupled with powerful on-the-fly error correction technology.With 8 NAND channels supporting the high-speed ONFi 2.3 and Toggle 1 flash interfaces, the LM87800 can access up to 1 terabyte of commodity NAND flash while also cost-effectively supporting today’s mainstream SSD capacities of 64 GB, 128 GB, 256 GB, and 512 GB. The LM87800 supports NAND flash from all major vendors including SLC, MLC and eMLC flash families.

Featured in Corsair’s groundbreaking Neutron Series SSDs, winner of the prestigious “Best of Computex 2012” award from Tom’s Hardware, Corsair’s Neutron are the industry’s first SSDs to deploy the LM87800 controller.Offered as a turn-key solution, the LM87800 comes complete with qualified and field-proven host interface and NAND management firmware, reference designs and documentation to enable customers to quickly design-in and bring to market leading-edge SSD products. LM87800 samples are available now.
