科学家实现近室温条件下单分子存储

Storing data in individual molecules： Molecular memory near room temperature

近日．一个由美国麻省理工大学、印度科学教育研究院等单位科学家组成的国际小组．对以往的“分子存储”实验技术进行了改良．使其能在摄氏零度左右运行．并使制造工艺大大简化。相关论文发表在《自然》杂志网站上。

Moore＇s law--the wellknown doubling of computer chips＇ computational power every 18 months or so--has been paced by a similarly steady increase in the storage capacity of disk drives. In 1980, a hard drive could store about a half-megabyte of data in a square inch of disk space; now, manufacturers are closing in on a million megabytes of data per square inch.
