□ Solutions to the Memory Wall: A New Memory Hierarchy and Data-Centric Computing
During the event, Samsung presented two main technological solutions to address the memory wall challenge, which are the introduction of a new memory hierarchy structure and the adoption of data-centric computing. The existing hierarchy is effective in processing small data quickly, but it faces limitations in handling large-scale data operations such as big data and machine learning, due to bottlenecks. This is why it is necessary to introduce a new hierarchy that maximizes system performance through active memory solutions such as the PBSSD and Memory Expander, which compensate for the performance gap between the existing and new structure.
Data-centric computing is a new form of computer architecture that significantly enhances system performance by performing computations directly where the data is stored. In particular, it dramatically improves the problem of system performance degradation due to the increase in data travel distance and time generated by next-generation applications such as machine learning, for which large-scale data processing is essential.
□ Efforts and Initiatives Toward Sustainable Computing
The system performance degradation that results from the memory wall also causes more energy to be spent on data processing, and addressing this issue is closely connected to sustainable computing, which pursues energy efficiency and reductions in power consumption. Samsung Electronics announced its new environmental strategy in September last year, which includes the goal of carbon neutrality by 2050. This strategy is a necessary response to a time in which global cooperation is required to reduce the large amount of greenhouse gas emissions generated by the massive increase in data processing. To achieve its overarching goal, Samsung has established and implemented further specific goals to minimize environmental impact in the fields of carbon, water, waste and pollutants.
Samsung has developed and applied its own Life Cycle Assessment (LCA) process to calculate and monitor the carbon emissions of all its semiconductor products, and it is also cooperating to create a more sustainable semiconductor ecosystem by joining IMEC’s3
Sustainable Semiconductor Technologies and Systems (SSTS) program.
Lastly, Samsung also used the platform of 2023 OCP APAC Tech Day to emphasize the need for continued open innovation. The OCP Experience Center located within the Samsung Memory Research Center (SMRC) on the Hwaseong campus serves as a foundation for partners, OCP member companies and academia to collaborate with IT stakeholders in order to solve technical challenges and further open-source development. Samsung expressed the hope to enable customers, partners and others to experience OCP-certified products that it develops and manufactures, as well as the intent to become a hub of open innovation by developing and validating solutions utilizing next-generation memory solutions and petabyte-scale storage.
The future of Samsung Electronics seems truly promising as it continues to address the memory wall and drive disruptive innovation in memory through technological solutions and open collaboration.
