Abstract:
A read operation method is provided for a flash memory array having a plurality of memory cells, wordlines, even bitlines, odd bitlines and a plurality of bitline transistors. The method includes pre-charging the plurality of even bitlines to about Vcc/n and pre-charging the plurality of odd bitlines to ground. The current flowing to/from a first bit location in each of the memory cells is selectively sensed. A logical state is determined from the sensed current for the first bit location in each of the memory cells. The method also includes pre-charging the plurality of odd bitlines to about Vcc/n and pre-charging the plurality of even bitlines to ground. The current flowing to/from a second bit location in each of the memory cells is selectively sensed. A logical state is determined from the sensed current for the second bit location in each of the memory cells.
