Abstract
A semiconductor device may include a number of memory banks, an output buffer that couples to the memory banks, a number of switches that couple a voltage source to the output buffer, and a stagger delay circuit. The stagger delay circuit may include a resistor-capacitor (RC) circuit that outputs a current signal that corresponds to a data voltage signal received by the RC circuit. The stagger delay circuit may also include a logic circuit that determines a strength of the current signal and sends a first gate signal to a first portion of the switches based on the strength.
