Abstract
A semiconductor device having multilevel memory cells is disclosed. In one embodiment, the device is operable to determine a state of a first bit of a memory cell by application of a first voltage to the memory cell, with the first voltage having a value to cause the memory cell to provide an output indicative of the state of the first bit. The device is further operable to select between a second voltage and a third voltage based on the output, and to determine a state of a second bit of the memory cell by application of the selected voltage to the memory cell, with the selected voltage having a value to cause the memory cell to provide an output indicative of the state of the second bit.
