AI Technical Summary
Technical Problem
In the process of reducing power consumption, the use of low-dropout linear regulators (LDOs) in existing DRAMs increases the memory area, making it difficult to reduce the area.
Method used
The data transmission circuit is divided into a first data path and a second data path, and different power supply voltages and ground voltages are configured for them. Different power supply voltages are transmitted through the first data path and the second data path respectively, thereby reducing the power consumption of the data transmission circuit.
Benefits of technology
Without increasing the memory area, the power consumption of the data transmission circuit is significantly reduced, and no additional circuitry is required.
