Abstract
The present invention provides a system and method for designing and modularly expanding multiport bitcells. A modular design approach is described that reduces the complexity of designing multiport bitcells while complying with DFM rules across various semiconductor fabrication providers. The modular design may be parsed into modules such as read port modules, write port modules, and pull-up modules that may be easily interconnected to build a multiport bitcell. These modules may also be independently sized and assembled to achieve desired read margins, write margins, static noise margins as well as read access times and write times.
