Abstract
Apparatuses, systems, and methods are presented for reading data. A controller may be configured to select a read mode from a plurality of read modes for reading data from a region of a non-volatile memory array. The plurality of read modes may include at least a time-based soft bit read mode. The controller may be configured to apply a set of bias conditions to cells of a region so that bit line currents associated with the cells of the region affect voltages at capacitors associated with the cells of the region. The controller may be configured to, in response to selecting a time-based soft bit read mode, read hard bits and soft bits for a region by sensing capacitor voltages resulting from an applied set of bias conditions, at multiple integration times.
