ABSTRACT:
The present invention concerns a method and apparatus for generating a global wordline signal without requiring a metal layer for the global wordline route across multiple arrays. The global wordline signal is generally cascaded between the various group arrays. A low voltage level is generally presented across the wordlines to the various arrays that are inactive to minimize the overall amount of current used by the circuit. Once a particular array is activated, the present invention boosts the signal to a high level which represents an active wordline for a selected array. The present invention uses a global wordline scheme that uses the local wordlines from the previous array to determine whether to bring the next array up to an active level.
