Speedy DDR SDRAM
Our DDR SDRAM allows applications to transfer data on both the rising and falling edges of a clock signal, doubling bandwidth and vastly improving performance over SDRAM. Basically, DDR gives you source-synchronous data capture at twice the clock frequency; i.e. 133 MHz equals DDR-266. To achieve this functionality, we use a 2n-prefetch architecture where the internal data bus is double the size of the external data bus, so data capture can happen two times each clock cycle.
DDR continues to be the ideal choice for many new designs, and will be on our road map for years to come. As such, we’re committed to long-term product support and availability.
If DDR seems like a good fit for your next design or product migration, please consult our DDR part catalog where we provided detailed specifications, including density, width, and data rate. You can also find more information below about our DDR products—including our plans for long term product and technical support.
