ALEXANDRIA, Va., Oct. 27 -- United States Patent no. 12,776,383, issued on Oct. 27, was assigned to Sandisk Technologies Inc. (Milpitas, Calif.).

"Multi sense time valley search in NAND" was invented by Albert Bor Kai Chen (Milpitas, Calif.), Longju Liu (Fremont, Calif.), Jiahui Yuan (Fremont, Calif.) and Anirudh Amarnath (San Jose, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Technology for multi sense time valley search in NAND memory. The memory cells are sensed multiple times for a single charging of the sense nodes. Also, the voltage to the control gates of the memory cells may be held at the same magnitude for each sensing. Optionally, the control gate voltage may be changed with the memory ce...
