SigmaQuad-IVe™ Family Overview
SigmaQuad-IVe ECCRAMs are the Separate I/O half of the SigmaQuad-IVe/SigmaDDR-IVe family of high performance ECCRAMs. Although similar to GSI's third generation of networking SRAMs (the SigmaQuad-IIIe/SigmaDDR-IIIe family), these fourth generation devices offer several new features that help enable significantly higher performance.
