Memory Controller - Double Data Rate Memory

Double Data Rate Memory

Double Data Rate DDR memory controllers are used to drive DDR SDRAM, where data is transferred on the rising and falling access of the memory clock of the system. DDR memory controllers are significantly more complicated than Single Data Rate controllers, but allow for twice the data to be transferred without increasing the clock rate or increasing the bus width to the memory cell.

Famous quotes containing the words double, data, rate and/or memory:

    What happens is that, as with drugs, he needs a stronger shot each time, and women are just women. The consumption of one woman is the consumption of all. You can’t double the dose.
    Ian Fleming (1908–1964)

    This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.
    Susan Sontag (b. 1933)

    You are more than entitled not to know what the word ‘performative’ means. It is a new word and an ugly word, and perhaps it does not mean anything very much. But at any rate there is one thing in its favor, it is not a profound word.
    —J.L. (John Langshaw)

    “I have done it,” says my memory. “I cannot have done it,” says my pride, refusing to budge. In the end—my memory yields.
    Friedrich Nietzsche (1844–1900)
