Publication number: 20240088246Abstract: Various embodiments of the present application are directed towards a control gate layout to improve an etch process window for word lines. In some embodiments, an integrated chip comprises a memory array, an erase gate, a word line, and a control gate. The memory array comprises a plurality of cells in a plurality of rows and a plurality of columns. The erase gate and the word line are elongated in parallel along a row of the memory array. The control gate is elongated along the row and is between and borders the erase gate and the word line. Further, the control gate has a pad region protruding towards the erase gate and the word line. Because the pad region protrudes towards the erase gate and the word line, a width of the pad region is spread between word-line and erase-gate sides of the control gate.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Inventors: Yu-Ling Hsu, Ping-Cheng Li, Hung-Ling Shih, Po-Wei Liu, Wen-Tuo Huang, Yong-Shiuan Tsair, Chia-Sheng Lin, Shih Kuang Yang

Publication number: 20230363155Abstract: Various embodiments of the present application are directed towards an integrated memory chip comprising a memory array with a strap-cell architecture that reduces the number of distinct strap-cell types and that reduces strap-line density. In some embodiments, the memory array is limited to three distinct types of strap cells: a source line/erase gate (SLEG) strap cell; a control gate/word line (CGWL) strap cell; and a word-line strap cell.

Further, in some embodiments, the three distinct strap-cell types electrically couple word lines, erase gates, and control gates to corresponding strap lines in different metallization layers of an interconnect structure. By spreading the strap lines amongst different metallization layers, strap-line density is reduced.Type: ApplicationFiled: July 19, 2023Publication date: November 9, 2023Inventors: Wen-Tuo Huang, Ping-Cheng Li, Hung-Ling Shih, Po-Wei Liu, Yu-Ling Hsu, Yong-Shiuan Tsair, Chia-Sheng Lin, Shih Kuang Yang
