Patent ID: 7486116

Claim:
A semiconductor device, comprising: a driver device having a first signal driver connected to a semiconductor device supply voltage and a second signal driver, the first and second signal drivers each comprising a pull-up transistor and a pull-down transistor, the first and second signal drivers adapted to jointly drive an output digital signal stream of data on a line connected to the first and second signal drivers; a signal driver control circuit section, said control circuit section enabling the second signal driver during an initializing phase of the semiconductor device when a voltage representation of the supply voltage is below a predetermined reference value, and disabling the second signal driver during the initializing phase of the semiconductor device when said representation of the supply voltage is above the predetermined reference value; wherein when the second signal driver is enabled, both the first and second signal drivers continuously and jointly drive the output signal, and when the second signal driver is disabled only the first signal driver drives the output signal; and wherein when the second signal driver is set to one of said enabled or disabled condition in the initializing phase, the second signal driver is maintained in said set enabled or disabled condition during a subsequent regular operational phase of the semiconductor device regardless of the value of the supply voltage.
