Abstract
An apparatus for controlling generation of pulses for refresh operations of a memory device having a pad to transfer information and to receive signals from an external interface. The apparatus includes a switch, coupled to a current source and to the pad receiving signals from the external interface. The switch outputs one of the signals from the current source or the pad in response to a switch control signal. An oscillator is coupled to the switch and generates the refresh operation pulses in response to the output from the switch.
