Using the concept for nonvolatile memories recently proposed by K. Shum, J.
Q. Zhou, W. Zhang, L. F. Zeng, and M. C. Tamargo [Appl. Phys. Lett. 71, 24
87 (1997)], a promising nonvolatile memory device has been designed and dem
onstrated using a III-V semiconductor quantum structure. Preliminary data o
n the device's stability and reliability reveals that further improvements
are possible on the cycling endurance and retention time. (C) 2000 American
