Microchip background


When we introduced our DDR SDRAM, it was revolutionary and pioneering technology. DDR allows applications to transfer data on both the rising and falling edges of a clock signal, doubling bandwidth and vastly improving performance over SDR SDRAM. 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.
