Abstract
Apparatuses and methods for triggering row hammer address sampling are described. An example apparatus includes an oscillator circuit configured to provide a clock signal, and a filter circuit. The filter circuit includes a control circuit configured to receive pulses of the clock signal and provide an output signal that represents a count number by counting a number of pulses of the clock signal and control a probability of enabling the output signal based on the count number. The filter circuit further includes a logic gate configured to pass one of the pulses of the clock signal responsive to the output signal from the control circuit being enabled and filter another of the pulses responsive to the output signal from the control circuit being not enabled.
