In response to determining that the second portion of the memory component has the amount of unused storage to store the data stored at the first data block, data stored at the first data block in the first portion of the memory component is relocated to a second data block in the second portion of the memory component. An error rate is evaluated on each word line in the first data block.

Abstract: Described herein are techniques for removing control of a display from an operating system. The disclosed techniques decouple operation of the physical display device from control of the operating system so that the display device may be powered down while not needed during streaming. The device driver for the graphics card, into which a display device cable is plugged, simulates operation of the display but allows the display to be powered down. Simulating the display involves properly responding to queries or commands from the operating system, and generating the signals that would be expected from the display device by the operating system. While simulated in this manner, whether the display device is actually powered down does not matter to the operation of an application being streamed, because the operating system still “believes” the display device is powered on. Thus application streaming is not interrupted by powering down the display device.
