Abstract
A replenish circuit for a semiconductor memory device, including a bias current generating unit adapted to generate a bias current, a frequency controllable oscillator adapted to receive the bias current and to provide an oscillating output, and a pulse generator adapted to receive the oscillating output and to generate first and second pulses as a function of the oscillating output, the second pulse being embedded in the first pulse, the first pulse causing the bias current generating unit to be connected to a power supply, and the second pulse being fed to sample-and-hold circuitry adapted to sample the bias current and hold the value thereof during the first pulse.
