A technique for reducing power consumption in a data storage device consisting of a number of data cells includes arranging the number of data cells in clusters, each cluster having more than one data cell having their data enable inputs connected together. A data write bus is provided to provide data enable signals to the data enable inputs of the number of data cells. A number of pass gates are respectively disposed between the clusters and the write data bus. The pass gates are selectively enabled to allow data enable signals to pass from the write data bus to the data enable inputs of the more than one data cell of a selected one or more of the clusters. A number of inverters may be respectively disposed between the number of pass gates and the clusters. A number of sustainer circuits may be respectively connected to the number of pass gates. Each of the pass gates may include a pair of field effect transistors which may be complementary field effect transistors. Each of the sustainer circuits may include a pair of back-to-back inverters.
