A Search Algorithm for the Worst Operation Scenario of a Cross-Point Phase-Change Memory Utilizing Particle Swarm Optimization.

In this paper, we propose a search algorithm to find the worst operation scenario of a cross-point array of a phase-change random access memory to enable a precise read margin evaluation. The search algorithm utilizes a particle swarm optimization method to find the worst scenario quickly and efficiently. In an experiment, the proposed algorithm improves the search speed by 39.3× compared with the...
