ECC TEK Provides ECC To NASA Missions

Solar Dynamics Observatory

NASA's Solar Dynamics Observatory, which uses ECC Tek's SSD error correction, lifted off from Cape Canaveral on February 11, 2010 on a five-year mission to study the sun. "You can think of the SDO spacecraft as containing a parallel-transfer, fault-tolerant SSD that uses DRAM chips instead of NAND Flash chips. It uses the same PRS ECC I have proposed for use in solid state disks. All the data collected by SDO is encoded by the PRS encoder, stored in the SSD and decoded by the PRS decoder. Multiple DRAM chips can fail with no loss of data or performance." ....Phil White

On June 23, 2009, NASA launched the Lunar Reconnaissance Orbiter (LRO) to conduct investigations for future lunar exploration. ECC Tek's patented parallel ECC is being used in the LRO to correct data sent back to earth. Our powerful ECC has proven successful by properly correcting data even in the highly damaging radiation environment of outer space.

NAND Flash

NAND Flash controller companies are licensing ECC Tek’s programmable binary BCH ECC. Binary BCH codes are recommended by the major NAND Flash manufacturers.

ECC Tek’s binary BCH designs for Flash are fast becoming the de facto standard in the industry. ECC Tek’s binary BCH ECC designs for Flash allow customers to vary the number of bits corrected and the page size, implement a variable or fixed delay, and minimize the gate count or latency.

Future Technology Concepts

ECC Tek has invented and patented methods and apparatus for encoding and decoding Reed-Solomon codes in a parallel and pipelined fashion. We see the potential to use this technology to create fault-tolerant hard disk drives (Parallel Reed-Solomon HDDs) and fault-tolerant solid state disks (Parallel Reed-Solomon SSDs).

About ECC Technologies

Since 1990 ECC Technologies (ECC Tek) has licensed forward error correction (FEC, ECC) for data communications and storage. We supply our customers with solutions not only to conventional error correction needs, but also to the challenging needs of high-speed, wide-bandwidth, fault-tolerant systems. These solutions can be in the form of hardware or software designs, all customizable to fit customer's applications. Other services we provide are assistance with error correction need analysis, assistance with testing, and support throughout the implementation of a design.
