Sony revealed as MRAM foundry for Avalanche

October 31, 2016 // By Peter Clarke
Sony Semiconductor Manufacturing Corp. has agreed to make spin-transfer torque (STT) magnetic random access memories (MRAMs) for Avalanche Technology Inc. (Fremont, Calif.)

Volume production of a perpendicular magnetic tunnel junction (pMTJ) style of STT-MRAM is expected from Sony early in 2017 on 300mm wafers at a variety of manufacturing nodes.

Avalanche said it is currently sampling discrete parts up to 64Mbit in capacity to customers and is now poised to ramp the first pMTJ-based MRAM memory in the industry to production in early 2017.

"STT-MRAM is an ideal solution for markets such as storage, automotive, IoT and embedded applications," said Petro Estakhri, founder and CEO of Avalanche Technology, in a statement.

Rival MRAM company Everspin announced it was sampling a 256Mbit memory earlier in 2016 and that it planned to sample a 1Gbit MRAM based on proprietary pMTJ spin-torque technology later this year.

Avalanche's STT-MRAM technology is backed by 229 awarded patents, the company said.
