Abstract

This invention discloses a voltage regulation control circuit for NOR memory, relating to the field of NOR memory technology. It includes a power supply module that provides two sets of operating power to the memory module: a first power supply and a second power supply. The memory module performs data storage and interaction. A power detection module can detect overvoltage or undervoltage states of the first power supply through set first undervoltage and first overvoltage thresholds, and detect overvoltage or undervoltage states of the second power supply through second undervoltage and second overvoltage thresholds. When overvoltage or undervoltage occurs in the first power supply but not in the second power supply, a switching control module will self-lock and control the power supply module to disconnect the first power supply. An auxiliary voltage regulator module will then regulate the voltage of the second power supply and supply power to the memory module. When the second power supply is overvoltage or undervoltage, power supply will be stopped. This NOR memory voltage regulation control circuit can maintain the voltage stability of the memory module, improving operating efficiency and circuit safety.
