Abstract
A device includes a memory array and a sense circuit coupled with the memory array. The sense circuit includes a sense node coupled with a data line of the memory array. A first sensing path includes a first transistor having a first gate coupled with the sense node. A second sensing path includes a second transistor having a second gate coupled with the sense node. A first threshold voltage of the first transistors differs from a second threshold voltage of the second transistor by a threshold voltage gap.
