The present invention provides a 6T SRAM including a first inverter, a second inverter, a first pass-gate transistor, and a second pass-gate transistor. The first inverter zs a first pull-up transistor and a first pull-down transistor. The second inverter includes a second pull-up transistor and a second pull-down transistor. The gate of the second pull-up transistor is coupled with the gate of the second pull-down transistor, and the drain of the second pull-up transistor is coupled with the drain of the second pull-down transistor. The SRAM can measure the trip voltage, the read disturb voltage, and the write margin by controlling the first bit line, the second bit line, the GND, the first word line, and the voltage source without changing of the physic parameter of the SRAM. |
