Abstract:
In a nonvolatile memory using floating gates to store charge, individual floating gates are L-shaped. Orientations of L-shaped floating gates may alternate in the bit line direction and may also alternate in the word line direction. L-shaped floating gates are formed by etching conductive portions using etch masks of different patterns to obtain floating gates of different orientations.
