Abstract: The present invention is directed to a system (100) maintaining chilled temperature in a cold storage (102) comprising: a plurality of coolant layers 104 uniformly placed on the roof of said storage (102); each coolant layer comprising multiple coolant plates (106) stacked in rows and columns; a compressor (110) generating airflow and circulating airflow in a circular pattern from top to bottom in said (storage 102); thereby maintaining temperatures in the range ?25° C. to +25° C.

Abstract: Positioning a block of graphics memory within a memory system so as to minimize the number of memory devices and/or banks of memory within memory devices occupied by the block of graphics memory so as to maximize the number of memory devices and/or banks of memory within memory devices that are not occupied by even a portion of the block of graphics memory, and thereby, maximize the number of memory devices and/or banks of memory within memory devices that may be placed into a lower power state without causing the block of graphics memory to become inaccessible so as to impair reading out graphics data to support refreshing an image on a display device.
