High throughput N-modular redundancy for error correction design of memristive stateful logic 下载免费PDF全文
Memristive stateful logic is one of the most promising candidates to implement an in-memory computing system that computes within the storage unit. It can eliminate the costs for the data movement in the traditional von Neumann system. However, the instability in the memristors is inevitable due to the limitation of the current fabrication technology, which incurs a great challenge for the reliability of the memristive stateful logic. In this paper, the implication of device instability on the reliability of the logic event is simulated. The mathematical relationship between logic reliability and redundancy has been deduced. By combining the mathematical relationship with the vector-matrix multiplication in a memristive crossbar array, the logic error correction scheme with high throughput has been proposed. Moreover, a universal design paradigm has been put forward for complex logic. And the circuit schematic and the flow of the scheme have been raised. Finally, a 1-bit full adder (FA) based on the NOR logic and NOT logic is simulated and the mathematical evaluation is performed. It demonstrates the scheme can improve the reliability of the logic significantly. And compared with other four error corrections, the scheme which can be suitable for all kinds of R-R logics and V-R logics has the best universality and throughput. Compared with the other two approaches which also need additional complementary metal-oxide semiconductor (CMOS) circuits, it needs fewer transistors and cycles for the error correction. 相似文献

The molecular thin films of Rose Bengal (RB) embedded in polymethyl
methacrylate matrix are fabricated by using the spin-coating
technique. The macroscopic current--voltage (I--V) characterization
of the film shows that the RB molecule has two conductance switching
states with a high ON/OFF ratio in ambient conditions. The infrared
spectra indicate that intermolecular hydrogen bonds can form in the
RB thin films after their hydrolysis in air. With the
first-principles calculations, we demonstrate that the hydrogen
bonds will be destroyed in concomitance with the conformational
change when the RB molecule switches to its high-conductance state
after applying a voltage. 相似文献
