Cypress Semiconductor Corp. Standard Sync SRAM

Cypress is the Synchronous (Sync) SRAM market leader with more than 2.7 billion cumulative units shipped, with lead times of six weeks or less, 99% or higher on-time delivery and legacy product support for up to 20 years. Cypress is the preferred SRAM supplier to customers in several market segments such as networking, automotive, consumer electronics, industrial, medical, aerospace and defense. Cypress has the industry™s broadest Sync SRAM portfolio with more than 2,300 different products. Rated #1 for performance and reliability, these products have industry leading Random Transaction Rate (RTR up to 2132 MT/s), FIT rates (less than 0.01-FIT/Mb) and innovative new features such as on-chip Error Correction Code (ECC). Cypress Sync SRAM products are suitable for systems running mission critical applications such as switches and routers, RADAR and signal processing, test equipment, automotive and military. Random Transaction Rate (RTR)Random Transaction Rate (RTR) is the number of fully random read or write transactions a memory can perform every second. It is measured in MT/s, or mega transactions per second. RTR is a critical metric in high performance applications, such as networking, where memory access is unpredictable. The QDR AdvantageThe QDR SRAM architecture provides the random memory access capabilities needed for networking and other high performance applications. In these applications, memory is a major bottleneck to reaching higher system performance. For example, in networking applications, each data packet requires several random memory transactions. Therefore, the packet processing rate of the system is dependent on how quickly the system can access memory. Cypress's QDR SRAM provides the RTR necessary to break system bottlenecks. Other memory technologies are optimized for high density. Although these memories perform well for compute applications as the main memory, they do not meet the needs of high performance applications that demand high RTR. QDR SRAM, on the other hand, is designed specifically for maximum RTR. QDR SRAM allows access to any two memory locations on every clock cycle, and performance never depends on which memory location was accessed in the previous clock cycle. With QDR SRAM, RTR is guaranteed. Cypress's QDR-IV SRAM provides RTR up to 2132 MT/s. This level of performance is critical to enable the next generation of high performance systems.
