SUNNYVALE, USA: GSI Technology Inc. announced immediate availability of the industry's first family of commercial, ultra-low error rate SRAMs—GSI’s ECCRAMs.
The new 72Mbit devices transparently encode and store error correction codes with every write and then read, decode and, if necessary, correct bit errors using a fast ECC algorithm. With no speed penalty, the device automatically corrects bit flips due to radiation particle strikes. Accelerated testing in high-energy particle beam tests shows that the SRAMs can be expected to demonstrate a vanishingly small Soft Error Rate (SER) of less than 0.002 FITs/Mb—a 5-order-of-magnitude improvement over comparable technologies with no on-chip ECC.
ECCRAMs are members of GSI’s 2nd and 3rd generation SigmaQuad and SigmaDDR SRAM families. They are available in a variety of packages and performance points, and are qualified for immediate volume production.
"Shrinking process feature sizes continues to make dealing with both Alpha and Neutron particle strikes more and more challenging,” said David Chapman, VP of Marketing and Applications Engineering at GSI Technology. "GSI has been leading the industry in addressing this problem with both process improvements and architectural adaptions for several years now; however, this new attack on the problem finally puts it to rest. Airborne applications are no longer an issue.”
