TSMC announced, during the company's virtual European technology symposium, that it is developing MRAM technologies for its 16nm FinFET platform. The company expects to offer flash-like configuration risk production starting in 4Q21 and RAM-like risk production scheduled for 4Q22.
The company also expects to "explore smaller geometries" for its MRAM (and RRAM) solutions. TSMC started offering 22nm MRAM in 2018.
An international team of researchers led by Israel's Bar Ilan University have developed a new type of MTJ that has four resistance states. The researchers also demonstrated how it is possible to switch between these four different states using spin currents.
The four-state design uses a structure that is in the form of two crossing ellipses instead of one of the standard magnetic layers of the MTJ. Such a design could be used to create multi-level MRAM which stores data more densely compared to current MRAM memories which only have two states in each MTJ.
Spin Memory (previously Spin Transfer Technologies) announced that it has developed a new innovative technology, called the Universal Selector, which will significantly improve the capabilities of existing and emerging memory technologies (including MRAM, DRAM and ReRAM) as it enables a novel way to design vertical cell transistors which achieves higher levels of performance, reliability and density.
Spin Memory’s Universal Selector is a selective, vertical epitaxial cell transistor whose channel has a low enough doping concentration that it operates in full depletion. For MRAM memory, the Universal Selector enables manufacturers to create 1T1R memory bitcells of 6F2 – 10F2 (6F2 – 10F2), enabling manufacturers to embed up to five times more memory in the same area footprint with minimal additional wafer processing costs.
Everspin Technologies reported its financial results for Q2 2020. Total revenues reached $11.8 million, up 37% from Q2 2019, and the GAAP net loss was $1.3 million (compared to a net loss of $3.7 million in Q2 2019). Cash and equivalents at the end of Q2 2020 were $12.9 million.
Everspin says it has extended its momentum into the second quarter, with record revenues of its 1Gb STT-MRAM product. Looking into Q3, Everspin says it sees a delay in new product introduction plans by customers, and so sees its revenues between $10 million and $10.8 million.
