Benefits of technology
The present invention is about a power generator for data transporting buffers of a memory apparatus. The power generator meets the requirements of high speed and low power consumption. The data line powers are generated by clamping the supply voltage according to the bias voltage. This ensures that the power consumption does not increase and the bandwidth of the memory apparatus is not reduced when the supply voltage is increased. Therefore, this technology allows for efficient power consumption and high data transfer rates.
Problems solved by technology
Therefore, when a plurality of data transporting buffers on the data lines are in transition, the biggest power consumption is happened.

Embodiment Construction
[0021]Reference will now be made in detail to the present preferred embodiment of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
[0022]Please referring to FIG. 1, FIG. 1 is a block diagram of a power generator 100 according to an embodiment of the present invention. The power generator 100 includes a bias voltage generator 110 and a voltage clamping circuit 120. The bias voltage generator 110 is coupled to the voltage clamping circuit 120, and the voltage generator 110 generates a bias voltage VBIAS according to a reference voltage. Te voltage generator 110 provides the bias voltage VBIAS to the voltage clamping circuit 120. The voltage clamping circuit 120 receives a supply voltage VCC and the bias voltage VBIAS, and the voltage clamping circuit 120 clamps a voltage level of the supply voltage VCC to generate a plurality of da...

The invention provides the power generator includes a bias voltage generator and a voltage clamping circuit. The bias voltage generator receives a reference voltage and generates a bias voltage according to the reference voltage. The voltage clamping circuit is coupled to the bias voltage generator. The voltage clamping circuit receives a supply voltage and the bias voltage and respectively outputs a plurality of data line power to the data transporting buffers by clamping the supply voltage according to the bias voltage. Wherein, the supply voltage is varied between a voltage range, and voltage levels of the data line powers are all constant.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The present invention generally relates to a power generator of a memory apparatus, and more particularly to the power generator for data transporting buffers of the memory apparatus.[0003]2. Description of Prior Art[0004]Along with the rapid development of science and technology at the present, a mobile electronic apparatus is necessary for a person for regular using. In mobile application, the power consumption is the most critical factor as times goes by. For a system with memory apparatus, a memory apparatus with high bandwidth and low power consumption is necessary.[0005]For meeting the high bandwidth demand, larger amount data lines for reading and writing operation are disposed in the memory apparatus. Therefore, when a plurality of data transporting buffers on the data lines are in transition, the biggest power consumption is happened. That is, it is an important subject for a designer of the memory apparatus for sa...
