This work addressed the technological limitation \nof an emerging memory technology known as Phase Change Memory (PCM). \u003C\/p\u003E\u003Cp\u003EPCM\n provides benefits such as non-volatility, low-power, high-density with \naccess speed comparable to DRAM, yet more scalable in feature size. \nIndustries have been investigating PCM as a candidate to replace DRAM, \nbut PCM\u0027s usability is hindered by its limited write endurance. Dr. Lee \nand his team proposed a novel, wear-leveling technique called security \nrefresh, which randomly shuffles the physical location of each memory \nblock to slow down wear-out caused by frequent writes to the same \nlocations. The scheme evens out the write distribution in the PCM space \nand obfuscates address access patterns to prevent worst-case writes or \nmalicious exploits. Security refresh can effectively extend PCM\u0027s \nlifetime to approach its theoretical limit, enabling its practical use \nas an integral part of the system memory for future computing systems. \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"Georgia Tech Named to This List for the First TIme"}],"field_summary":[{"value":"\u003Cp\u003EA paper written by Hsien-Hsin Sean Lee and his research team is the first ever from Georgia Tech to be chosen for\u003Cem\u003E IEEE Micro\u003C\/em\u003E\n magazine\u0027s \u0022Top Picks\u0022 issue.
