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.

“On the death of a friend, we should consider that the fates through confidence have devolved on us the task of a double living, that we have henceforth to fulfill the promise of our friend’s life also, in our own, to the world.”

“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“Strange that the vanity which accompanies beauty—excusable, perhaps, when there is such great beauty, or at any rate understandable—should persist after the beauty was gone.”
—Mary A. [Elizabeth, Countess Von] Arnim (1866–1941)
“Tsars and slaves, the intelligent and the obtuse, publicans and pharisees all have an identical legal and moral right to honor the memory of the deceased as they see fit, without regard for anyone else’s opinion and without the fear of hindering one another.”
—Anton Pavlovich Chekhov (1860–1904)
