Elpida Memory develops resistance RAM prototype

Jan 24, 2012

Elpida Memory, the world's third largest Dynamic Random Access Memory ("DRAM") manufacturer, today announced the development of its first-ever high-speed non-volatile resistance memory (ReRAM) prototype. As the ReRAM prototype was made using a 50-nanometer process technology it has a memory cell array operation of 64 megabits, one of the highest densities possible for ReRAM. The prototype was jointly developed with the New Energy and Industrial Technology Development Organization (NEDO), a Japanese-funded public institution. Further work on ReRAM development is being conducted with Sharp Corporation, the National Institute of Advanced Industrial Science and Technology (AIST, another Japanese public institution) and the University of Tokyo.

ReRAM (Resistance Random Access Memory) is next-generation semiconductor that uses material which changes resistance in response to changes in the . This new type of non-volatile memory can store data even when the power supply is turned off. Its most attractive feature is that it can read/write data at high speeds using little voltage. While (DRAM) is superior to existing non-volatile memory with respect to read/write speeds and endurance, DRAM quickly loses data when the power supply is removed. NAND flash memory, a leading example of nonvolatile memory, retains data even when the power is removed but has performance measures that are inferior to DRAM.

ReRAM, on the other hand, is a type of semiconductor memory that contains the advantages of both DRAM and NAND . It has a write speed of 10 nanoseconds, about the same as DRAM, and write endurance of more than a million times, or more than 10 times greater than NAND flash.

Elpida plans to continue development toward a 2013 goal of volume production of ReRAM in the gigabit capacity class using a 30nm process technology. If the high-speed durable new memory can be provided at low cost it will contribute enormously to a reduction of memory power consumption. This will make it an attractive storage (recording medium) option in a variety of information technology products, such as smartphones, tablet devices and ultra-thin light notebook PCs.

Elpida continues to develop process migration and other technology related to DRAM and at the same time promotes the development of ReRAM as a promising next-generation memory that can substitute for DRAM functions.

Ironic of Elpida to bring up ReRAM as possible DRAM replacement, when it is trying so hard to survive in DRAM. Even in ReRAM, they are way behind Samsung.
