  • Patent number: 7860172
    Abstract: A k-to-2k decoder is provided. Within the final stage of a k-to-2k decoder is a plurality of word line drivers. These word line drivers utilize clocking signals to fire word lines to a memory array. However, power consumption by clocks has become a serious issue with the increase component density on silicon wafers. To alleviate the problem, signals from the first stage of the k-to-2k decoder provide enablement signals to Local Clock Buffers (LCBs) that allow the word line drivers to fire. The enablement signal reduces the number of active buffers and signals carried to word line drivers, reducing power consumption.
