Refresh 회로 구현에 따른 2T DRAM-based PIM Chip 면적 분석
최희재(Hui-Jae Choi),심원보(Wonbo Shim) 대한전자공학회 2023 대한전자공학회 학술대회 Vol.2023 No.6
The emergence of AI-based conversational services has led to a focus on the high performance semiconductor market. Technology for processing large amounts of data is essential, and to process such data, it is necessary to address the data bottleneck and power consumption increase issues in the von Neumann architecture. Processing-in-memory (PIM) acts as a key solution to these bottleneck and power consumption. In this paper, we added a refresh circuit to implement 2T DRAM in the synaptic array of the PIM chip. As a result, we analyzed the synaptic array area and the PIM chip area with the addition of the refresh circuit, and finally presented research directions for the optimal PIM chip design that can have advantages in terms of density.

The cost of simulation modeling, the expertise required, and the pains of starting a new each time are impediments to more wide spread adoption of simulation technology. In addition, one of the most critical problems in the field of computer simulation today is the lack of published models and physical objects within the World Wide Web (WWW) allowing such distribution. From the viewpoint of WWW as distributed model repositories, it can be assumed that very many simulation models exist on the web. This paper is based on the premise that WWW is a distributed repository. Design Pattern, web-oriented techn ogy like Java and COREA, which are especially to cope with distributed objects, are introduced and discussed in detail for integration of simulation model. In this paper an architecture of model integration is proposed, which presents the whole procedure of model integration and how the Internet technologies are connected in. The central focus of this research is on the technical realization of integrating simulation models as distributed objects
