Electronic Data Collection and Storage
At the end of the semester it is expected that the student achieves a strong knowledge of the different types or architectures and memories (volatile and nonvolatile) currently available, with particular focus in the flash technology. The student is expected to gain competences related to the electrical characterization of memory devices. The course will also focus the emergent memory technologies and the student will gain a deep inside into this area where new research activities will be developed in the Materials Science Department.

This curricular unit has classes TP and practical.
TP classes are suported by powerpoint slides in english and will be teached in either portuguese or english language. In each class, references about the concepts discussed in class will be provided to assit on further reading.
Practical classes will be Exercize Solving concerning the themes talked during the TP classes, held in a classroom, or laboratory classes held in a Laboratory, where exploratory experimental activities will be performed about the technologies and themes discussed in the theoretical classes.
The evaluation of GEI has a theoretical component (50%) and a practical component (50%).
Theoretical Component (50%):
2 to 3 theoretical tests (T1,T2, T3), whre the final theoretical grade will be obtained by the average of the tests. It is mandatory atheoretical average grade higher that 9.5 values (out of 20 value scale) to achieve aprouval at GEI valores
Practical component (50%)
15% - Lab Work Group (Analysis of thin film RERAM Memories) – Group
20% - State of the art of selected themes – Group
10% - Individual test on selected themes (with T2) – Individual
5% - Individual miniQuizz during the semester and participation - Individual
Student participation and autonomy (5%)
Frequency is mandatory and is given by participation of the prctical classes (at least 2/3 of the classes). The final grade will be the average of the grades of all practical components..
