Abstract
This invention provides a method, system, and medium for implementing a hybrid memory system based on HBM, including: initializing and establishing a hybrid memory controller, creating a heat monitoring table and an address translation table; the hybrid memory system receiving access requests; reallocating the storage location of data according to its heat, updating the address translation table, and redirecting access requests; migrating and caching data according to the address translation table, and completing the access request. This invention, taking advantage of the high bandwidth characteristics of HBM, divides HBM into c-HBM and m-HBM regions and performs detailed heat classification of data, significantly improving the access speed of hot data, reducing data migration overhead, and effectively reducing the overall access latency of the memory system. Compared to traditional memory systems that only add a small amount of HBM, this invention significantly improves the overall access speed of the memory system while providing more memory space, performing excellently under various workloads and showing good market prospects and application value.
