Samsung has just announced the successful creation of the world's first MRAM-based in-memory computing chip, made with A.I. computing in mind.
Samsung has just revealed the world’s first in-memory computing based on MRAM . The team described these innovative findings in a paper published by Nature.
In the press release that describes Samsung’s research, the company explains that memory chips are typically used for storing data, while data computing is executed in separate processor chips. Iin-memory computing is a technique that performs both tasks within a memory network. In-memory computing has been attempted with the use of other no-volatile memory types, in particular resistive random access memory and phase-change random access memory However, the use of MRAM has proven difficult, and Samsung explains that this is due to the low resistance of this memory type. When used in the standard in-memory computing architecture, MRAM doesn’t benefit from the desired power reduction.
The research led to the development of an MRAM array chip capable of in-memory computing while addressing the aforementioned problem of low resistance presented by individual MRAM devices. The array chip was then tested by performing various A.I. computing tasks, and it performed excellently. Samsung reports that the chip hit 98% accuracy in the classification of handwritten digits and 93% accuracy in being able to tell faces apart from the scenery.
