SOT-MRAM To Challenge SRAM


In an era of new non-volatile memory (NVM) technologies, yet another variation is poised to join the competition — a new version of MRAM called spin-orbit torque, or SOT-MRAM. What makes this one particularly interesting is the possibility that someday it could supplant SRAM arrays in systems-on-chip (SoCs) and other integrated circuits. The key advantages of SOT-MRAM technology are the pr... » read more

Building An MRAM Array


MRAM is gaining traction in a variety of designs as a middle-level type of memory, but there are reasons why it took so long to bring this memory to market. A typical magnetoresistive RAM architecture is based on CoFeB magnetic layers, with an MgO tunneling barrier. The reference layer should have zero net magnetization to make sure that it doesn’t influence the orientation of the free lay... » read more

Challenges In Making And Testing STT-MRAM


Several chipmakers are ramping up a next-generation memory type called STT-MRAM, but there are still an assortment of manufacturing and test challenges for current and future devices. STT-MRAM, or spin-transfer torque MRAM, is attractive and gaining steam because it combines the attributes of several conventional memory types in a single device. In the works for years, STT-MRAM features the ... » read more
