Abstract
The present disclosure provides an off-chip driver (OCD) and an associated DRAM. The OCD operates in a power domain. The power domain works under a minimum system voltage and a maximum system voltage. The OCD is configured for providing a drive current to an output pad. The OCD includes a pull-push circuit. The pull-push circuit is coupled to the output pad. The pull-push circuit includes a current source circuit. The current source circuit includes a VCCS. The VCCS is configured to provide, in response to an operation voltage, an impedance with respect to the output pad, wherein the operation voltage ranges between the minimum system voltage and the maximum system voltage.
