  • Patent number: 7177176
    Abstract: In embodiments of the present invention, a static random access memory (SRAM) device has an array of memory cells in columns and rows. An individual memory cell includes two PMOS pull-up devices coupled to two NMOS pull-down devices. In READ mode and/or STANDBY/NO-OP mode of a column, the two PMOS pull-up devices are effectively strengthened by forward biasing the PMOS n-wells or by utilizing a lower threshold voltage PMOS device by implanting a lower halo dose in the PMOS device. In WRITE mode of a column, the two PMOS pull-up devices are effectively weakened by reverse biasing the PMOS n-wells or by coupling the sources of the NMOS devices to virtual ground (VSSi).
