Balanced Modulation for Nonvolatile Memories
[article]
2012
arXiv
pre-print
This paper presents a practical writing/reading scheme in nonvolatile memories, called balanced modulation, for minimizing the asymmetric component of errors. ...
Balanced modulation has suboptimal performance for any cell-level distribution and it can be easily implemented in the current systems of nonvolatile memories. ...
It enables balanced modulation to be adaptive to a variety of channels characters, hence, it makes balanced modulation applicable for most types of nonvolatile memories. ...

Anisotropic modulation of magnetic properties and the memory effect in a wide-band (011)-Pr0.7Sr0.3MnO3/PMN-PT heterostructure
2015
Scientific Reports
In addition, we find that the anisotropic, nonvolatile modulation of magnetic properties gradually diminishes as the temperature approaches FM transition, indicating that the nonvolatile memory effect ...
However, a nonvolatile tuning of the magnetic state by the electric field, namely the memory effect, is required for information storage. ...
It was assumed that such a nonvolatile magnetic memory effect was due to the modulated energy balance between coexisting FM and charge-ordered antiferromagnetic (COAFM) phases in the phase-separated manganite ...

Ultra-compact nonvolatile phase shifter based on electrically reprogrammable transparent phase change materials
[article]
2022
arXiv
pre-print
The volatility not only compromises energy efficiency due to their demand for constant power supply, but also precludes them from emerging applications such as in-memory computing. ...
To circumvent this limitation, we introduce a novel phase shifting mechanism that exploits the nonvolatile refractive index modulation upon structural phase transition of Sb_2Se_3, a bi-stable transparent ...
Such nonvolatility is also interesting for in-memory computing, 34, [40] [41] [42] and configure-once applications, such as optical trimming and transient coupler for wafer-scale photonic testing. 43 ...
