The article provides a detailed technical comparison of SRAM, DRAM and HBM, explains their roles in modern AI GPUs such as the H100, discusses training and inference memory placement, and evaluates emerging ideas like High‑Bandwidth SRAM and High‑Bandwidth Flash, concluding that all three memory types will coexist in future AI systems.
As large‑model inference demand outpaces training, the decode stage hits a memory‑wall that GPUs cannot efficiently cross; SRAM’s on‑chip bandwidth and low‑energy access open a path forward, though capacity and process limits still pose challenges.
This article explains the fundamentals of data storage in computers, covering the concepts of RAM, the differences between static SRAM and dynamic DRAM, and how memory controllers manage refresh cycles and address translation to enable efficient read/write operations.
This article provides a comprehensive overview of semiconductor memory technologies, covering their classification into volatile and non‑volatile, detailed descriptions of ROM, PROM, EPROM, EEPROM, FLASH, SRAM, DRAM, and guidance on selecting the appropriate memory for system design.
