In order to foster situated learning in a virtual community of practice, we developed a multiuser , real-time, 3D car-driving simulation environment. In such a situation-based learning environment, the availability of enough appropriate learning situations is crucial for success. However, we experienced that often a collaborative usage of the system does(More)
This paper reviews the DRAM technology challenges for overcoming the 50nm barrier. First the product requirements and barriers to shrink the DRAM cell beyond 50nm will be addressed. Then the technology solutions for DRAM cell capacitor, cell transistor, and support transistors are presented. Key enablers arc high aspect ratio cell capacitor structures, new(More)
