Abstract:
Techniques are provided for sensing a signal associated with a memory cell capable of storing three or more logic states. To sense a state of the memory cell, a charge may be transferred between a digit line and a node coupled with a plurality of sense components using a charge transfer device. Once the charge is transferred, one or more of the plurality of sense components may sense the charge with one of a variety of sensing schemes. Based on the charge being transferred using the charge transfer device and each sense component sensing the charge, a logic state associated with the memory cell may be determined. The number of sensed states may be correlated to the number of sense amplifiers. The ratio of the number of states read by the first sense component and the second sense component to the number of sense components may be greater than one.
