发明名称 Cell structure for dual port SRAM
摘要 A multi-port SRAM cell includes cross-coupled inverters each including a pull-up transistor and at least a pair of pull down transistors. The SRAM cell includes first and second access ports coupled to first and second word line conductors, each access port including a first pass gate transistor coupled to the data storage node and a second pass gate transistor coupled to the data bar storage node, each pass gate transistor being coupled to a respective bit line conductor, wherein the pull down transistors of the first inverter are formed in a first active region, the pull down transistors of the second inverter are formed in a second active region, the pass gate transistors coupled to the data storage node are formed in a third active region and the pass gate transistors coupled to the data bar storage node are formed in a fourth active region.
