A multiplier based on memristor RRAM

Abstract

The invention provides a multiplier based on a memristor RRAM. The multiplier of the voter logic is given based on the original adder, the structure of the Wallace tree is adopted for operation, the multiplication operation is converted into the corresponding addition operation, and by utilizing the Wallace tree structure, a plurality of n-Bit numbers are added up to 2n-Bit numbers, and each fulladdition operation can be performed simultaneously by using voter logic. The multiplier of the invention improves the overall running speed and reduces the area of the device.

Description

technical field [0001] The invention relates to the field of non-volatile memory calculation, in particular to a multiplier based on resistance random access memory (RRAM, Resistive Random Access Memory, RRAM for short). Background technique [0002] With the continuous development of memristors and the increasingly prominent von Neumann bottleneck, the integration of storage and computing has been continuously mentioned by various scholars. In recent years, with the deepening understanding of memristors, it has now Not only is it used as a new type of storage material, but the potential of memristors in logic operations has been continuously explored. [0003] Since Hewlett-Packard proposed implication logic, the research on logic operations based on memristors has begun to flourish. Scholars have continuously proposed different improvement schemes and other new logic algorithms to improve the efficiency of operations and the number of units of the device, so as to ease ope...

[0003] Since Hewlett-Packard proposed implication logic, the research on logic operations based on memristors has begun to flourish. Scholars have continuously proposed different improvement schemes and other new logic algorithms to improve the efficiency of operations and the number of units of the device, so as to ease operations and storage. However, as far as the current research is concerned, it is still based on a full adder and its simpler logic, and rarely involves complex logic operations. This is because these logics currently designed The operation is complicated, parallel operation is not possible, and the uniformity of the device is high, which also hinders the development of memristor-based logic operation.
