  • Patent number: 7561488
    Abstract: Provided is a wordline driving circuit and method for a semiconductor memory, in which the wordline driving circuit includes an address decoding signal generator and a wordline voltage supplier. The address decoding signal generator receives a first row address decoding signal (URA) and generates a delayed URA signal (PXID). The wordline voltage supplier has a pull-up transistor for providing the PXID signal to a selected wordline in response to a second row address decoding signal (LRA). The address decoding signal generator sets the PXID signal to a floating state before the selection of the wordline to prevent a leakage current from flowing through the pull-up transistor in a standby mode.
