A system and method for analyzing the timing requirements of a memory array are disclosed. The memory cell circuitry used in the original memory array may utilize two bi-directional passgate transistors which are both used during read and write operations on the memory cell, e.g., where signals can flow across the passgate transistors in two directions. A model of the memory array may be created according to a memory cell model that uses uni-directional passgate transistors. Modeling the memory array with uni-directional circuitry may enable a static timing analysis tool to determine the critical path through the memory array. Once the critical path has been determined from the model of the memory array, a dynamic simulation of the critical path in the original memory array may be performed to accurately determine the timing requirements of the original memory array.
