Dual-port SRAM connection structure
Abstract:
The present disclosure provides a static random access memory (SRAM) cell. The SRAM cell includes first and second inverters cross-coupled for data storage, each inverter including at least one pull-up device and at least two pull-down devices; at least four pass gate devices configured with the two cross-coupled inverters; at least two ports coupled with the at least four pass-gate devices for reading and writing; a first contact feature contacting first two pull-down devices (PD-11 and PD-12) of the first inverter; and a second contact feature contacting second two pull-down devices (PD-21 and PD-22) of the second inverter.
