Patent number: 8559255Abstract: A system and methodology that can minimize disturbance during an AC operation associated with a memory, such as, program, read and/or erase, is provided. The system pre-charges all or a desired subset of the bit lines in a memory array to a specified voltage, during an AC operation to facilitate reducing AC disturbances between neighboring cells. A pre-charge voltage can be applied to all bit lines in a block in the memory array, or to bit lines associated with a selected memory cell and neighbor memory cells adjacent to the selected memory cell in the block. The system ensures that source and drain voltage levels can be set to desired levels at the same or substantially the same time, while selecting a memory cell. This can facilitate minimizing AC disturbances in the selected memory cell during the AC operation.Type: GrantFiled: August 8, 2012Date of Patent: October 15, 2013Assignee: Spansion LLCInventors: Sung-Yong Chung, Zhizheng Liu, Yugi Mizuguchi, Xuguang Alan Wang, Yi He, Ming Kwan, Darlene Hamilton, Sung-Chul Lee, Guowei Wang, Nancy Leong
