摘要： A non-volatile memory device includes an array of non-volatile memory cells. When programming the memory cells, a voltage supply source is used that includes multiple independent charge pumps. The independent charge pumps supply the programming voltage to different ones of bit lines in the array of memory cells. Using multiple charge pumps tends to reduce output voltage fluctuations and thereby reduce power loss.

摘要： Techniques for programming a non-volatile memory device, such as a Flash memory, include floating source lines of memory cells based on a data pattern that is being programmed to the memory device. The source lines to float are selected such that a distance between drain bit lines and source bit lines of different memory cells in a row is maximized. In this manner, leakage current between these drain bit lines and source bit lines can be decreased.

摘要： 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.
