Abstract
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.
