Abstract
Memristor-based dividers using memristors-as-drivers (MAD) gates. As a result of employing MAD gates in memristor-based dividers, such as binary non-restoring dividers and SRT dividers, the number of delay steps may be less than half than the number of delay steps required in traditional CMOS implementations of dividers. Furthermore, by using MAD gates, memristor-based dividers can be implemented with less complexity (e.g., fewer memristors and drivers). As a result, by the memristor-based dividers using MAD gates, the speed and complexity of a wide variety of arithmetic operations is improved.
Claims9
An SRT divider, comprising:
- a first memristor, wherein said first memristor is connected to a first switch and a second switch;
- a second memristor connected in parallel to said first memristor, wherein said second memristor is connected to a third switch, wherein a fourth switch is connected to said first and second memristors;
- a fifth switch, a sixth switch, a seventh switch, an eighth switch, a ninth switch and a tenth switch connected to said second memristor;
- a third memristor connected in parallel to said second memristor, wherein said third memristor is connected to an eleventh switch, a twelfth switch and a thirteenth switch;
- and
- a fourth memristor connected in parallel to said third memristor, wherein said fourth memristor is connected to a fourteenth switch, a fifteenth switch, a sixteenth switch, a seventeenth switch, an eighteenth switch and a nineteenth switch.
