ADS Simulation: A New Methodology for DDR4 Testing

Application Notes

DDR memory designers are under constant pressure to go faster, use less power, and work within an ever-shrinking footprint. Gaining design insight early in the design cycle offers the opportunity to take corrective action quickly to make sure product quality, interoperability, and time-to-market goals are met. Success depends on efficiency and reduced design cycles to control costs.

DDR4, the most recent generation of Double Data Rate SDRAM memory, enables significantly higher bandwidth for data transfer than DDR3, along with evolutionary improvements in density and power. Designers are embracing the latest DDR4 memory technologies to increase system data rates beyond 2400 Mb/s and push designs to record speeds of up to 3200 MT/s. However, while DDR4’s higher data rates offer distinct performance advances, they also present new challenges in defining appropriate specifications and effective simulation techniques for developers to assure compliance.
