This paper presents a non-conventional program pulse approach for Phase-Change Memories (PCMs). The cell programming curve is experimentally evaluated and discussed. The proposed Set-Sweep program pulse allows compensating for spreads in cell physical parameters. This ensures a better SET condition for marginal cells and adequately narrow SET distributions, which results in improved read margin. Experimental results have been collected from a 8-Mb BJT-selected PCM demonstrator. The effectiveness of the proposed program pulse has been proved by comparing cell distributions obtained on the whole array by means of a conventional SET box and a Set-Sweep program pulse, respectively.
