Description of Achievement and Assessment Methods

60 minutes examination with the following elements:
- Written examination, closed books, no notes
- It consists of questions that cover the knowledge of all the diverse memory technologies that have been explained, hand calculations and drawings that cover the ability to solve and explain problems arising from the used technologies and related background questions. Examples for typical exam questions are the questions in the exercises.

Content

Without memory technologies we would not be able to live our connected lifestyle. Memory is the core of our tablets, PCs, smart phones, servers, cloud services, deep learning hardware and the basis of almost all complex electronics. Understanding how different memory technologies work and where their limitations are is crucial for most applications.

Memory technology operates at the forefront of semiconductor technology and production. Memory technology uses the most advanced lithography tricks and the latest transistor designs in combination with novel electronic materials. Therefore, you will touch base with the latest challenges in nanoelectronics and learn how to live with them or how to mitigate them.

The lecture will discuss technology details, limitations and challenges along the memory hierarchy in data storage systems.
Outline:
semiconductor memories:
-SRAM
-DRAM
-Soft errors (SER)
-Flash
-FeRAM
-MRAM
-PCRAM (3D XPoint)
-OTP like e-Fuse, Antifuse, eMemory, Kilopass, Synopsis, NSCore
Emerging Memories:
-resistive memory technologies (Memristor etc.)
-3D memory technologies
-mechanical and magnetic memories:
-magnetic tape storage
historical memory devices

Teaching and Learning Methods

Lecture with discussion
readings assignments, case studies
Individual and group exercises
In addition to the individual student's methods a consolidated
knowledge is targeted by repeated lessons in exercises and tutorials.
Teaching method:
During the lectures students are instructed in a teacher-centered style. The exercises are held in a student-centered way.
