Dual-port static random access memory cell layout structure

摘要

The disclosure provides a dual-port static random access memory cell layout structure, including a pull-down transistor layout structure, a first and a second pass transistor layout structure. Each of them includes an active region pattern and a polysilicon pattern; and contact hole patterns. The active region pattern of the pull-down transistor layout structure and the first pass transistor layout structure are connected together, and share the contact hole pattern at one end. The active region pattern of the pull-down transistor layout structure and the second pass transistor layout structure are connected together, and share the contact hole pattern at the other end. The disclosure optimizes the dual-port static random access memory cell layout structure, improves the influence of the optical fillet effect on device matching, strengthens the performance including read-write crosstalk of the pull-down transistor under the situation of the same area, and increases the read current.
