US 2026/0029946 A1 · VOLTAGE MONITORING BY A MEMORY SYSTEM

Abstract

Methods, systems, and devices for voltage monitoring by a memory system are described. An application specific integrated circuit (ASIC) may be configured to provide feedback to one or more controllers of a memory system indicating whether a current sensed from an alternating current (AC) voltage source satisfies a threshold. The ASIC may output a flag in response to the current sensed by the ASIC satisfying the threshold, and the memory system may perform power management operations by adjusting operating parameters in response to the flag. The ASIC may be configured to generate token information that estimates a total current budget for the memory system in accordance with a power consumption at components of the memory system (e.g., AC components, direct current (DC) components, open NAND flash interface (ONFI) components), and the memory system may perform power management operations in response to the total current budget satisfying a threshold.
