  • Patent number: 9892791
    Abstract: Systems and methods for reducing sensing time for sensing data states stored within a plurality of memory cells are described. In some cases, the ramping of a word line connected to the plurality of memory cells may be delayed until a threshold current corresponding with a particular number of erased memory cells of the plurality of memory cells has been met or exceeded. The threshold current may be compared with a summation of a first set of detection currents corresponding with a first set of memory cells of the plurality of memory cells that have been sensed to be in a conducting state while the word line is set to a voltage level for sensing erased memory cells. The threshold current may be set based on a chip temperature and/or a particular number of bit errors that occurred during a prior sensing operation.
