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.

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, the sensing circuitry includes left and right hand portions which have separate cache access lines, but are connected to a common output bus. A full data word can be output at a time by using a half word from the left hand portion and a half word from the right hand portion. Or, the sensing circuitry can be configured so that a full data word is output at a time from the left or right hand portion. One implementation provides an N-bit bus and N input paths for each of the left and right hand portions. Another implementation provides an N-bit bus and N/2 input paths for each of the left and right hand portions.
