GlobalFoundries company decided to start in the near future to mass production of non-volatile memory type ST-MRAM (Spin-Torque Magnetoresistive Random-Access Memory, magnetoresistive RAM with spin transfer). Taken as a base to take technology - cell structure - the company Everspin Technologies. This developer has already announced its development of solvency - to date around the world sold about 40 million. Memory chips ST-MRAM with the label Everspin. On the base of this memory are nonvolatile buffers for SSD and blocks volatile memory for logging transactions.
Memory ST-MRAM combines unique features such as performance level and even DRAM SRAM, non-volatility and conditionally infinite resistance to wear. Structurally ST-MRAM is simple enough. One transistor controls the process of reading and writing. The secret is in the combination of the two magnetic layers with a thin layer of insulator. One layer has a constant magnetization, the second - free. Sufficiently strong current can change the direction of magnetization of the free layer.
GlobalFoundries company promises to invest the money for the technology Everspin at its 300-mm plants in relation to the 40-nm and 28-nm LP-process technology. Related Products :
