Memory Products

For over two decades, GSI Technology has developed and marketed high performance memory products, including SRAMs and LLDRAMs. These memories are incorporated primarily in high-performance networking and telecommunications equipment, such as routers, switches, wide area network infrastructure equipment, wireless base stations and network access equipment. In addition, our SRAMs serve the ongoing needs of the military, aerospace, industrial, test and measurement equipment, automotive, and medical markets. Due to the performance characteristics of our products and the breadth of our product portfolio, GSI Technology is a leading provider of high performance SRAMs and LLDRAMs.
