In summer 2013 Crossbar company presented cohort of multiple developers RRAM memory (ReRAM) or resistive RAM . In contrast to the widely proven methods saturation depleted insulator layer in the RRAM cell oxygen atoms, Crossbar method involves creating a controlled and reversible amorphous silicon strands of silver ions. Since cell Crossbar actual semiconductor manufacturing technology RRAM Crossbar is relatively easy to bear on modern CMOS-process technologies. In 2016, Crossbar company promised to start licensing stage of RRAM technology to major producers of semiconductors.
Recently, one of the world's largest contract semiconductors manufacturer - the Chinese company Semiconductor Manufacturing International Corporation (SMIC) announced that it has concluded with the company Crossbar partnership agreement on the commercialization of resistive memory production . On the base of the license agreement, SMIC company is taken to produce RRAM to everyone in the form of built-in microprocessors and SoC-volatile memories. RRAM units will be integrated into SoC processors within the 40-nm process technology. The company expects that the superior performance of RRAM beneficial supplement in the form of solutions and SoC processors for wearable electronics, items with a connection to the Internet, smartphones, tablets and various automation.
Until now experienced RRAM memory chips company Crossbar manufactured using 110-nm process technology and a three-layer structure of a capacity up to 4 Mbps. Tests showed that the RRAM memory array can be up to 20 times faster NAND-flash, up to 20 times more economical consumption and withstand 10 times the erase / write cycles. RRAM Crossbar Memory may be organized as a one transistor cell and the resistance as well as a single n-transistor and the resistor (cells). In the first case will be the highest access speed in the second - the highest recording density. It will be interesting to know what are the characteristics of RRAM Crossbar blocks in 40nm design SMIC.
