Patent for ferrite memory (1949)
Pa Okutobala 21, 1949, wasayansi waku America waku China waku China An Wang adapereka chilolezo chotchedwa kukumbukira kwa ferrite. Lingaliro loyamba la kugwiritsa ntchito zida za ferromagnetic pakuzindikira kukumbukira lidabadwa mu 1945 m'malingaliro a J. Presper Eckert ndi Jeffrey Chuan Chu a Moore School ku University of Pennsylvania.
