Power Shaping Method for SSD controller
Modern SSD controllers employ a wide range of power management techniques, including clock and activity control, dynamic voltage and frequency scaling, power gating, and adaptive voltage optimization. These techniques are highly effective and essential, and in practice, achieving optimal power efficiency requires applying all of them aggressively. However, as NAND flash operations dominate system power consumption, especially under high parallelism, precise control of NAND power becomes increasingly critical and difficult to achieve using local, reactive mechanisms alone.This talk presents a system-level power shaping approach centered on NAND power control through a centralized power budget engine. In this model, baseline I/O-related power is treated as a steady background load, while array activity power—driven by read and program operations—is explicitly managed as a constrained resource. By shaping how and when NAND operations consume this budget, the controller can regulate total power behavior without interfering with existing circuit- and block-level power-saving techniques.
