GSI Memory Interface Solutions for Altera FPGAs and ASIC Applications


GSI Technology offers SRAMs and Low Latency DRAMs needed for most Stratix, Arria, and Cyclone FPGA, or HardCopy ASIC applications.
 

GSI is also the first SRAM vendor to provide memory controller IP for FPGA users. IP to support use of of our ground-breaking SigmaQuad-IIIe™ and SigmaDDR-IIIe™ SRAM families, the fastest production SRAMs in the world, is currently in development. Please contact your GSI Representative for more information.
