ABSTRACT:
The present invention discloses a CFI bit line decoder for a memory device that is capable of storing common flash interface data. In the preferred embodiment, the CFI bit line decoder has at least one bit line decoder circuit including at least one pass gate and a plurality of bit line pass gates, wherein each pass gate is electrically connected with at least one pass gate. In addition, the CFI bit line decoder includes at least one CFI storage circuit that has at least one storage cell electrically connected with the bit line decoder circuit. Each storage cell is in turn electrically connected with the bit line pass gate of the bit line decoder circuit. During CFI mode, a vertical address signal is used to enable a respective pass gate and a CFI address signal is used to enable a respective storage cell. A read circuit is then used to sense the logic state of the storage cell so that a peripheral device can use the data.
