Static random access memory cell and operating method thereof capable of reducing leakage current
A static random access memory cell includes first and second cross-coupled inverters, a write transistor and a read transistor. The first inverter has a first latch node and the second inverter has a second latch node. The write transistor is coupled in series with a wordline transistor between the first latch node of the first inverter and a bitline. The read transistor is coupled between the bitline and a reference terminal and has a control terminal coupled to the first latch node of the first inverter. A method of operating the static random access memory cell includes enabling the wordline transistor during a write operation, and enabling the write transistor during the write operation. The reference terminal is set to floating during the write operation.
