Avalanche Technology raises $33 million in a new funding round

pMTJ STT-MRAM developer Avalanche Technology announced that it closed its latest funding round led by Thomvest Ventures, having raised $33 million.

Avalanche currently brands its MRAM chips as P-SRAM (persistent SRAM) devices. The new funds will enable the company to develop higher-density P-SRAM devices. In addition, Avalanche says it will develop the higher densities of "persistent DRAM" required for the next generation of machine learning architectures.

Avalanche Technology starts to sample 32/64 Mbit STT-MRAM chips

STT-MRAM developer Avalanche Technology announced that it began to sample STT-MRAM chips. Avalanche's proprietary perpendicular magnetic tunnel junction (pMTJ) cells are manufactured in a high volume, low cost, standard CMOS 300mm process.

Those first sample chips are 32Mbit and 64Mbit in size, and offer an industry-standard SPI interface built on a 55nm-node foundry process. Avalanche is also offering its STT-MRAM technology (which they brand as AvRAM) under license as embedded memory for integrated SOC designs.

Crocus Nano Electronics successfully tests its 90 nm pMTJ STT-MRAM tech

Crocus Nano Electronics (CNE) announced successful test results for its 90 nm pMTJ STT-MRAM technology. The company says it has developed unique materials that are able to deliver high data retention, tolerance to external magnetic fields and low switching currents. The company expects to produce its first engineering samples in later in 2018.
