Abstract

In the present invention a bit line decoder scheme is described that connects data and voltage to a plurality of bit lines of a dual bit flash memory array. The bit lines are connected to a plurality of intermediate data lines by a first decoder unit and the intermediate data lines are connected to a plurality of data lines of the sense amplifiers by a second decoder unit. In one embodiment the voltage is connected to a selected bit line through a separate decoder unit and in a second embodiment the voltage is connected through the decoder unit connected to the intermediate data lines.
