Next generation nonvolatile memory "RRAM" can mount 1 TB of storage on one chip

Compared with conventional flash memory, the power consumption is only one-twentieth, the writing speed is 20 times, and the durability is ten times even at half the size High speed and high performance memory "RRAMVenture companyCrossbarDeveloped. "Next-generation nonvolatile memory" is singing, and 1 TB of storage can be loaded on a very small single chip.

Although the capacity of storage incorporated in PCs and smartphones is increasing year by year, the power consumption has increased, the number of times of discharging and charging has increased, and the life of the battery has been shortened. As a new technology to break through this situation, Crossbar announced on August 5 is "Resistive RAM (RRAM)". Since the power consumption of the conventional flash memory is much less than 1 / 20th, the battery life of the terminal is expected to increase from several weeks to one month, long and one year by using RRAM.

The size of the RRAM is 200 square mm, which is smaller than the postage stamp, but it is possible to mount 1 TB of storage equivalent to the capacity to record 250 hours of HD movies here. Also, because RRAM can be stacked on top of each other, it will be possible to incorporate several TB of storage in the terminal.

According to Crossbar, the memory array of RRAM is already in production, and it is planning to sell it as a product and plan a license to another company. The RRAM technology itself is a simple structure consisting of three layers, so manufacturing is not difficult and preparations for commercialization are in place.


Memory cellThe structure consists of three nonmetal bottom electrodes, switching medium made of amorphous silicon, and top electrode made of metal, the structure sticking to simplicity is the same as the conventional structureCMOSIt can be integrated into the production line of the system. RRAM has acquired 30 technical patents so far and has been optimized for codes of conventional NOR type and NAND type flash memory for circulation to the standalone chip market. Crossbar also completed the device using this RRAM,SoCSales plans are progressing as the first product to the market.
