ABSTRACT:
A method and structure for disconnecting shorted bitlines from a dynamic random access memory circuit includes supplying a precharge voltage to equalization lines in the integrated circuit, supplying a negative voltage to wordlines in the integrated circuit, activating equalization devices connected to the bitlines and the equalization lines and maintaining the precharge voltage and the negative voltage until a short between one of the bitlines and one of the wordlines causes a corresponding equalization device of the equalization devices to have a permanently elevated threshold voltage.
