Abstract
Systems, circuits, and methods are disclosed for charge sharing. In one such example system, a first line is configured to be driven to a first voltage representative of data to be placed on the first line and then precharged to a first precharge voltage. A second line is configured to be driven to a second voltage representative of data to be placed on the second line and then precharged to a second precharge voltage. A charge sharing device is coupled between the first line and the second line. The charge sharing device is configured to selectively allow charge from the first line to flow to the second line after the first and second lines are driven to the respective first and second voltages representative of data to be placed on the respective lines.
Claims25
An apparatus, comprising:
- charge sharing circuitry coupled between a segment of a first line and a segment of a second line and configured to share charge between the segment of the first line and the segment of the second line prior to precharging the segment of the first line or the segment of the second line.
An apparatus, comprising:
- a first line with a first segment and a second segment coupled to each other;
- a first driver coupled to the first segment of the first line and configured to drive the first line to a first voltage representative of data;
- a second line with a third segment and a fourth segment coupled to each other;
- a second driver coupled to the third segment of the second line and configured to drive the second line to a second voltage representative of data;
- a first charge sharing device coupled to the first segment of the first line and the third segment of the second line;
- and
- a second charge sharing device coupled to a second segment of the first line and the fourth segment of the second line.
A method, comprising:
- driving a plurality of line segments to a plurality of respective logic levels representative of data, the plurality of line segments including a segment of a first line and a segment of a second line;
- sharing charge between the segment of the first line and the segment of the second line through a charge sharing device coupled between the segment of the first line and the segment of the second line.
