The Shift to Memory-Centric Computing Architectures

The provided text explores the transition from processor-centric to memory-centric computing to address the performance and energy bottlenecks caused by massive data movement. Modern systems face significant challenges as DRAM technology scaling reaches its limits, leading to increased latency, higher power consumption, and serious security vulnerabilities like RowHammer and RowPress. To combat these issues, the authors propose the adoption of Processing-in-Memory (PIM), which integrates computational logic directly within or near data storage components. The sources distinguish between two primary PIM strategies: Processing-Using-Memory (PUM), which leverages the internal analog properties of memory chips for parallel operations, and Processing-Near-Memory (PNM), which places logic layers close to memory circuitry. Beyond hardware design, the text emphasizes the need for intelligent memory controllers and a redesigned software stack to support this sustainable, high-performance architecture. Ultimately, the research advocates for a fundamental shift in how systems handle data-intensive workloads like machine learning and genome analytics to ensure future scalability.
