Gravitational wave bursts produced by supermassive binary black hole mergerswill leave a persistent imprint on the space-time metric. Such gravitationalwave memory signals are detectable by pulsar timing arrays as a glitch eventthat would seem to occur simultaneously for all pulsars. In this paper, wedescribe an initial algorithm which can be used to search for gravitationalwave memory signals. We apply this algorithm to the Parkes Pulsar Timing Arraydata set. No significant gravitational wave memory signal is founded in thedata set.
