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.

“...the shiny-cheeked merchant bankers from London with eighties striped blue ties and white collars and double-barreled names and double chins and double-breasted suits, who said “ears” when they meant “yes” and “hice” when they meant “house” and “school” when they meant “Eton”...”

“To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.”
—F. Scott Fitzgerald (1896–1940)
“Writing a book I have found to be like building a house. A man forms a plan, and collects materials. He thinks he has enough to raise a large and stately edifice; but after he has arranged, compacted and polished, his work turns out to be a very small performance. The authour however like the builder, knows how much labour his work has cost him; and therefore estimates it at a higher rate than other people think it deserves,”
—James Boswell (1740–1795)
“Beauclerc: You’ve got a good memory for one who drinks.
Eddie: Drinkin’ don’t bother my memory. If it did, I wouldn’t drink. I couldn’t. You see, I’d forget how good it was. Then where’d I be? I’d start drinkin’ water again.”
—Jules Furthman (1888–1960)
