Abstract: Sensing techniques and associated circuitry are provided for use with a memory device. The techniques are suited for sensing operations involving even-numbered or odd-numbered bit lines. In one approach, a mapping between caches and sense amplifiers in a sensing circuit is modified by using dual data buses. One bus is used for same-tier transfers and the other is used for cross-tier transfers. Each tier comprises a set of sense amplifiers and a corresponding set of caches. This approach does not require a modification of the input/output path which is connected to the sensing circuitry.
