主题：夏普搞清了RRAM的机理，将在2010投产 -- 千僧

关于下一代不挥发存储器ＲＲＡＭ的基础技术开发

夏普与产业技术综合研究所共同研究，开发了能以闪存的100倍高速改写的下一代不挥发

存储器“ＲＲＡＭ※1”的新型高速改写方式的基础技术※2。

这是通向实用化的第一步成果，今后将继续开发集成化技术和精细加工技术，向实用化迈进。

ＲＲＡＭ是通过金属氧化膜的电阻变化来记忆信息的存储器单元，因为可以以低电压来

高速驱动，作为低耗电大容量高速改写的下一代存储器备受业界期待。但是，作为

ＲＲＡＭ的基础的金属氧化膜的电阻变化机理一直未被搞清，难以做出ＲＲＡＭ的特长的

元件。

这次，本公司与产业技术综合研究所共同研究，着眼于ＲＲＡＭ存储单元记忆信息的电阻

变化部分之外的阻抗部分，开发了至今未加控制的阻抗成分在写入和清除信息时发生

变动的“高速单极开关方式”。本来需要正负二个电源对ＲＲＡＭ进行写入和擦除、

现在只要单一电源，电路构成更简单并成功地使存储单元进行工作。这样，能低耗电且高速改写的ＲＲＡＭ的单元构造大幅简单化，单元尺寸也能做得更小。并且，因为用与一般的ＣＭＯＳ处理高度一致的材料、既存的生产线就能使用。

今后，推进切实研究开发存储元的集成化技术和精细加工技术，解决面向实用化的课题。

Fundamental technology of the next generation non- volatilization memory RRAM as for development sharp, high-speed entry of approximately 100 times that flash memory possible next generation non- volatilization memory “RRAM * developed the fundamental technology regarding the new high-speed rewriting system of 1” with the collaborative research of the independent administrative corporate body industrial technology research institute, * 2. This is the result of the 1st step which is directed to utilization, in the future, it continues, further research and development such as integration technology, and microprocessing technology starts aiming toward utilization. RRAM with the memory device which designates the change of electric resistance of the metal oxide film as information of memory, is expected low and from the fact that drive of the element is possible in high speed, as the next generation memory which high speed can rewrite the bulk data low by electric power consumption at voltage. But, actualization of the element where behavior of resistance change of the metal oxide film which is the basic part of RRAM is not elucidated, utilizes the merit of RRAM was difficult. This each time, this corporation, observes to the resistant component other than the resistant change part where information of the memory device of RRAM is remembered depending upon the independent administrative corporate body industrial technology research institute and collaborative research, this resistant component which has not been controlled so far, designates information as the value which differs at the time of time elimination of entry, developing “high-speed unipolar switch system”. It became possible to do the entry elimination of RRAM whose former plus and minus two power source is necessary, with single power source we succeeded in operating the memory device with simple circuit constitution. Because of this, low and simplifying the cell structure of RRAM whose high-speed rewriting is possible substantially by electric power consumption, it is possible to make cell size small. Furthermore, because the material whose consistency of general CMOS process is high is used, also diversion of the existing production line is possible. In the future, integration technology and microprocessing technology etc of the memory device, furthermore it implements the research and development which becomes steady, it starts tackling the topic solution which is directed to utilization.
