ABSTRACT: Due to the high device density and the advent of multiple bits per cell, modern nonvolatile memories are characterized by a non-deterministic behavior. We focus on phase-change memory (PCM), whose memory cell can be seen as a programmable resistor, and use information theory tools to investigate how the cell structure influences the storage capacity of this memory technology. In particular, we numerically compute the storage capacity of two known cell structures, i.e., the series cell, and the parallel cell. The results suggest that, in practical scenarios, the parallel cell structure is characterized by significantly larger storage capacity.

ABSTRACT: This paper reports on the successful application of very-high-performance robotics in the electrical testing of multichip modules using only two probes, breaking with the old traditional array of probes as the primary test method. Complete production line tools include two high-speed Hummingbird® probing robots and precise x-y tables to carry them and a fast, accurate opens-shorts test. To ensure fast probe placement without damaging the part under test requires real-time control hardware and software to operate with extreme precision, flexibility, and programmability to accommodate any part. Finally, because a module can have nearly 100,000 points to be probed, computing an optimal path for the two probes to take for full testing of a part can greatly reduce test time.

ABSTRACT: Autonomic personal computing is personal computing on autonomic computing platforms. Its goals combine those of personal computing with those of autonomic computing. The challenge of personal autonomic computing is to simplify and enhance the end-user experience, delighting the user by anticipating his or her needs in the face of a complex, dynamic, and uncertain environment. In this paper we identify the key technologies that enable autonomic behavior as distinguished from fault-tolerant behavior. We give some examples of current autonomic behavior and some general considerations for an architecture that supports autonomic personal computing. We identify its challenges to standards and technology developers and conclude with some guidance for future work.
