摘要： An apparatus and method for monitoring memory system performance and controlling an operating parameter is provided. A plurality of digital events indicative of memory system operations is detected, from which a subset of digital events to count is periodically selected, the subset being those digital events occurring during a sampling window time interval. Responsive to each digital event of the subset, a transistor is switched on to conduct current from a power supply to a capacitor. The transistor is biased by the capacitor to operate in a constant current region providing a substantially fixed amount of charge added to the capacitor responsive to each digital event of the subset. The operating parameter is controlled responsive to the charge accumulated in the capacitor, representative of the count of digital events in the subset. In one embodiment, the sampling window time interval is selected pseudo-randomly within a periodic base time interval.

摘要： A spray cooling system for semiconductor devices. An ink-jet type spray device sprays droplets of a cooling fluid onto the semiconductor devices. The devices vaporize the liquid, which gets passed through a roil bond panel, or other heat exchanger, and is pumped into a spring loaded reservoir that feeds the spray device.

摘要： A low-cost high aspect ratio skived heatsink with high performance ducting in order to optimize airflow over and through the skived fins. The skived heatsink can additionally have formed channels or extruded holes for insertion of a heatsink pipe therein. A thermally enhanced compound is used between the heatsink and heatpipe to provide a low thermal resistance between the parts. The heatpipe is expanded to optimally fill the channel or hole by injecting pressured fluid into the pipe before sealing the pipe with working fluid, or via heating of a sealed pipe and expansion of the working fluid therein. A partitioned cooling system can additionally be used, one partitioned section having high volume airflow with low static pressure, and another partitioned section using higher velocity ducted air over a plurality of skived heatsinks.
