摘要： A DRAM controller component generates a timing signal and transmits, to a DRAM, write data that requires a first time interval to propagate from the DRAM controller component to the DRAM and to be sampled by the DRAM on one or more edges of the timing signal, a clock signal that requires a second time interval to propagate from the DRAM controller component to the DRAM, and a write command, associated with the write data, to be sampled by the DRAM on one or more edges of the clock signal. The DRAM controller component includes series-coupled delay elements to generate respective incrementally delayed signals, and a multiplexer to select one of the delayed signals to time the transmission of the write data, such that transmission of the write data is delayed based on a difference between the first time interval and the second time interval.

摘要： Described is a memory system in which the memory core organization changes with device width. The number of physical memory banks accessed reduces with device width, resulting in reduced power usage for relatively narrow memory configurations. Increasing the number of logic memory banks for narrow memory widths reduces the likelihood of bank conflicts, and consequently improves speed performance.

One topology is programmable to support rail-to-rail or half-supply termination. Another topology selectively includes fixed or variable filter elements, thereby allowing the termination characteristics to be tuned for different levels of speed performance and power consumption. Termination voltages and impedances might also be adjusted.
