Section 2: The Core Principles and Necessity of PIM Technology – Why Is It Gaining Attention Now?
What if computation could be performed directly inside memory without moving data?
The current semiconductor technology ecosystem faces a fundamental problem: memory and processors are physically separated. In traditional chip architectures, data moves from memory to the processor and then back to memory. This process consumes enormous power and causes delays in computation speed.
Processing-In-Memory (PIM) technology completely overturns this paradigm. By performing computations directly within memory, it is designed to drastically reduce the energy waste caused by data movement. It's as if data is processed right where it resides.
The Core Principle of PIM Technology: Integration of Memory and Computation
To understand PIM technology, one must first grasp the limitations of traditional architectures. In conventional systems, the CPU fetches data from memory, performs computation, and stores the results back in memory. The more this ‘round trip’ is repeated, the more the system’s bandwidth becomes saturated and power consumption increases.
PIM fundamentally solves this problem by integrating computation units inside the memory chip itself. Calculations occur right where the data is stored, minimizing data movement distance. The main benefits achieved through this approach are:
- Reduced latency: With no data movement delay, computation speeds increase dramatically.
- Increased bandwidth: Constraints on data flow between memory and processor ease, boosting throughput significantly.
- Improved energy efficiency: Power consumption caused by long-distance data transfer within the chip drops drastically.
Why Is PIM Gaining Attention Now?
The power demand of AI data centers worldwide is exploding. As the data processing requirements for AI model training and inference increase exponentially, existing semiconductor technology solutions are no longer sufficient. This is why global giants like NVIDIA and Huawei are investing massive resources into developing high-performance computing chips.
PIM is regarded as a key technology to solving AI infrastructure’s power consumption challenge. It lowers data center power costs and enables more computations per unit of power. PIM’s efficiency is especially maximized in scenarios that require large-scale matrix computations during AI model training.
