Samsung Electronics develops world's first artificial intelligence HBM-PIM
Next-generation new concept that adds processor functions required for computational tasks inside the memory
The story of the case / Reporter Park Yeon-pa] = Samsung Electronics developed the world's first HBM-PIM (Processing-in-Memory) that combines a memory semiconductor and an artificial intelligence processor.
PIM (Processing-in-Memory) is a next-generation new concept convergence technology that adds processor functions necessary for computational tasks inside the memory. Samsung Electronics developed HBM-PIM with artificial intelligence engine on HBM2 Aquabolt, which is used for high-speed data analysis such as supercomputer (HPC) and AI, using PIM technology.
HBM2 (High Bandwidth Memory) Aquabolt refers to the second-generation high-bandwidth memory semiconductor mass-produced by Samsung Electronics in January 2018. When HBM-PIM is installed in an AI system, the performance of the system using the existing HBM2 is approximately doubled and the system energy is reduced by more than 70%.
In addition, by supporting the existing HBM interface as it is, customers using HBM can build a powerful AI accelerator system through HBM-PIM without changing hardware or software. AI accelerator refers to dedicated hardware to run artificial intelligence.
Recently, as the application area of artificial intelligence has been expanded and technology has been advanced, the demand for high-performance memory has continuously increased, but it was difficult to overcome the limitations of the von Neumann structure with the existing memory.
The von Neumann architecture is a method used in most computers today, in which the CPU loads and executes instructions from the memory, and stores the results in a memory device sequentially. In this process, if the amount of data exchanged between the CPU and memory increases, the processing of work is delayed.
To overcome this, Samsung Electronics installed an artificial intelligence engine in each bank inside the memory and maximized parallel processing to increase performance. In addition, HBM-PIM can perform arithmetic processing inside the memory, reducing data movement between the CPU and memory, thereby increasing the energy efficiency of the AI accelerator system. Bank refers to the minimum logical unit when composing main memory.
Samsung Electronics succeeded in commercializing HBM-PIM by incorporating these innovative technologies into the DRAM process, and released the thesis at ISSCC, the world's top academic society in the semiconductor field.
“HBM-PIM is the industry's first artificial intelligence customized PIM solution that can maximize the performance of AI accelerators. I will go out.”
“HBM-PIM is a remarkable achievement in terms of performance and energy efficiency for AI applications. I look forward to it.”
In the first half of the year, Samsung Electronics plans to complete test verification by mounting HBM-PIM in various customer's AI accelerators, and plans to strengthen cooperation with customers to standardize the PIM platform and build an ecosystem.
