Abstract
A hierarchical DRAM sensing apparatus and method which employs local bit line pairs and global bit lines. A word line selects the cells in a cluster of sense amplifiers, each of the amplifiers being associated with a pair of bit lines. One of the local bit lines is selected for coupling to global bit lines and a global sense amplifier. Clusters are located in a plurality of subarrays forming a bank with the global bit lines extending from each of the banks to the global sense amplifier.
