1Power
If high voltage is generated by the voltage generator, then the semiconductor memory device can perform memory operations, but current consumption increases
Solution Approach 1:
The patent implements dynamic resistance adjustment in the variable resistance unit based on the target voltage level. The resistance value changes dynamically according to the control signal, which is generated based on the relationship between the pumping voltage and target voltage. This dynamic adaptation allows the system to optimize current consumption while maintaining the required voltage generation capability for memory operations.
Solution Approach 2:
The patent changes the resistance parameter of the variable resistance unit according to the target voltage requirements. By adjusting the resistance value in response to control signals that reflect the voltage relationship, the system optimizes the operating parameters to reduce current consumption while maintaining adequate voltage generation for memory device operation.
2Use of energy by moving object
If resistance is reduced to lower current consumption, then power efficiency improves, but voltage regulation becomes more difficult
Solution Approach 1:
The patent employs a feedback mechanism where the control signal is generated based on the relationship between the pumping voltage and the target voltage. The variable resistance unit adjusts its resistance in response to this control signal, creating a closed-loop system that continuously monitors and adjusts the voltage output. This feedback ensures stable voltage regulation while maintaining reduced current consumption through optimized resistance values.
Solution Approach 2:
The regulator circuit automatically adjusts the resistance of the variable resistance unit based on the voltage relationship between the pumping voltage and target voltage. The system self-regulates without external intervention, maintaining optimal resistance values that balance current consumption reduction with voltage regulation stability through its inherent feedback mechanism.
