| 總結: | Modern computer architecture incorporates three principal memory technologies: DRAM,
SRAM, and Flash memory. However, due to the scaling limitation of charge-based memory
technologies, emerging memory technologies are looking to replace these conventional
memory technologies by introducing a new storage class memory (SCM). It combines the high
speed and endurance characteristics of DRAM with the non-volatility of Flash Memory, which
is urgently needed to fulfill the computing needs of this internet-of-things era. Conductive
bridge random access memory (CBRAM) stands out as one of the most promising candidates
for future memory technology, which relies on the migration of metal ions and subsequent
redox reactions. Its appeal lies in its low operating voltage, minimal energy consumption,
exceptional scalability, large memory window, and versatile switching characteristics.
Our main objective is to enhance our comprehension of the operating principle and
performance characteristics through various tests, such as current-voltage measurement and
direct current (DC) endurance, while simultaneously striving to enhance its overall reliability.
In this final year project (FYP), device characterization of Ag/GeTe/GeS/Pt-CBRAM device is
extensively studied. Therefore, this report delves into an extensive literature review
encompassing the different memory technologies, offering comprehensive insights into their
respective operating principles and performance characteristics. Additionally, it explains the
experimental methodologies employed in conducting the tests, providing detailed explanations
of the procedures and setups utilized. Furthermore, this report analyses and discusses the
outcomes of these tests, deriving insightful conclusions regarding the device behavior and
performance of the tested devices. |
