  • SRAM for SNM measurement
    Patent number: 5946226
    Abstract: In an SRAM for SNM measurement, the original word line of the SRAM cell for SNM measurement is divided into two segments for SNM measurement, wherein one segment is connected to the first node of the SRAM cell for SNM measurement, another segment is connected to the second node of the SRAM cell for SNM measurement. In addition, an adjacent word line adjacent to the SRAM cell for SNM measurement is connected to the SRAM cell for SNM measurement to form the word line of the SRAM cell. Therefore, the process of the SRAM for SNM measurement can be improved only by modifying the mask for the layout of the polysilicon layers in conventional ones.
