Abstract:
A control circuit is configured to connect to a cross-point memory array in which each conductive line, such as a bit line or word line, is connected to a transistor pair comprising a pMOSFET in parallel with an nMOSFET. When selecting a memory cell to be read, a voltage of a first conductive line may be pulled up using the pMOSFET in a conductive state while the nMOSFET is in a non-conductive state. Further, when reading the selected memory cell, the parallel nMOSFET of the first conductive line may be in a conductive state.
