1. , a kind of test macro of phase transformation memory device unit is characterized in that described test macro is made up of main control computer, pulse signal generator, derived digital signal, micro-control probe station and conversion link;

  • Wherein, by general purpose interface bus main control computer is linked to each other with derived digital signal with pulse signal generator;

    Umbilical cable by control card makes pulse signal generator link to each other with the micro-control probe station with derived digital signal;

    Main control computer switches between pulse signal generator and derived digital signal by control card control probe station;

    Two probes of micro-control probe station contact with the upper and lower electrode of phase transition storage respectively, constitute a storage unit.
