1Use of energy by moving object
If existing level conversion circuits are used to convert signal levels, then signal conversion function is achieved, but power consumption is high and element occupation area is large
Solution Approach 1:
The voltage conversion circuit is divided into two independent modules: a driving circuit that generates a first signal with voltage level less than the first voltage, and a receiving circuit that converts the first signal to a second signal with voltage level equal to the first voltage. This segmentation allows each module to be optimized independently, reducing overall power consumption and element occupation area while maintaining the signal conversion function.
2Area of stationary object
If a simple structure is used to reduce element occupation area, then area is reduced, but signal conversion reliability may be compromised
Solution Approach 1:
The first signal acts as an intermediary between the driving circuit and the receiving circuit. The driving circuit generates the first signal with reduced voltage level, and the receiving circuit uses this intermediate signal to produce the final second signal at the required voltage level. This intermediary approach allows the receiving circuit to operate at full voltage for reliable output while the driving circuit operates at reduced voltage for lower power consumption and smaller area.

AI summary
A voltage conversion circuit and a memory are provided. The voltage conversion circuit includes a driving circuit and a receiving circuit. The driving circuit is powered by a first voltage, and outputs a first signal at an output end, a voltage of a high level of the first signal being less than the first voltage. The receiving circuit is powered by the first voltage, receives the first signal at a first input end, and receives a sampling signal at a second input end. The receiving circuit is configured to output a second signal according to the sampling signal, and a voltage of a high level of the second signal is equal to the first voltage.
