Abstract

The invention relates to a nonvolatile Boolean logic operation unit, a nonvolatile Boolean logic operation method and a nonvolatile Boolean logic operation device. The nonvolatile Boolean logic operation unit comprises a diode and a phase change storage unit; the positive electrode of the diode serves as a first pulse signal input end to receive a first pulse signal, the negative electrode of thediode is connected to one end of the phase change storage unit, the other end of the phase change storage unit serves as a second pulse signal input end to receive a second pulse signal, and a corresponding operation method is designed to achieve logic operation. Compared with the prior art, according to the invention, the nonvolatile Boolean logic enables the calculation unit and the storage unitto be fused; the data processing process is put into the storage unit, and the calculation result is directly stored in the phase change storage unit, so that the performance and energy consumption problems caused by frequent data carrying are relieved, the logic operation steps are simplified, the time required for data transmission is shortened, and the calculation and storage integrated operation is realized.

Description

technical field

[0001] The invention relates to the field of semiconductor devices, in particular to a nonvolatile Boolean logic operation unit, method and device. Background technique

[0002] Traditional computer operations are based on the von Neumann architecture. In this structure, computing and storage are two completely separate units. The computing unit reads data from the memory and calculates according to the instructions. After completing the calculation and processing, it returns to the memory for storage. The rapid development of information technology has brought the computer field into a data-centric era of big data. The explosive growth of data scale and the separation of storage and computing architecture make the computing speed slower and slower, resulting in storage walls and data computing. Energy efficiency ratio bottleneck problem. In order to solve this problem, constructing a phase-change memory non-volatile logic operation method that integrates co...
