The invention provides a flash memory array structure and a method for programming the same, which relates to a technical field of nonvolatile memories in ultra large scale integrated circuit fabrication technology. The flash memory array of the present invention includes memory cells, word lines and bit lines connected to the memory cells, wherein the word lines connected to control gates of the memory cells and the bit lines connected to drain terminals of the memory cells are not perpendicular to each other but cross each other at an angle; the control gates of two memory cells adjacent to each other along the channel direction between every two bit lines are controlled by two word lines, respectively, drain terminals thereof are controlled by two bit lines, respectively, and source terminals thereof are shared. The present invention also provides a method for programming the flash memory array structure, which can realize a programming with low power consumption.
