A circuit for reducing current leakage in hierarchical bit-line architectures includes a sense amplifier having transistors, the sense amplifier coupled to bit-lines of cells in a memory array, the sense amplifier configured for detecting stored data from one of the cells; an output latch having transistors, the output latch selectively coupled to a global bit-line of the sense amplifier having a logical state, the output latch configured for selectively reading out stored data from one of the cells through the global bit-line; and a transmission gating device coupled between the sense amplifier and the output latch for selectively coupling the sense amplifier to the output latch correspondingly eliminating a first leakage path and forming a second leakage path, the first leakage path being between the sense amplifier and the output latch, the second leakage path formed within the sense amplifier.
