ABSTRACT:
A dual port memory is implemented in complementary (e.g., CMOS) technology so as to allow simultaneous uncontested read operations to the same memory cell. This is achieved by accessing one node of a bistable static cell through a n-channel and a p-channel access transistor. The opposite node is typically left unconnected to external access means. This technique also reduces the area required to implement the memory cell as compared to prior art NMOS techniques. If desired, an arbitration circuit can be included to arbitrate between simultaneous read/read or read/write operations on the same cell from the two ports.
