World's first MRAM-based in-memory computing:

Samsung Electronics today announced its demonstration of the world's first in-memory computing based on MRAM (Magnetoresistive Random Access Memory).

[...] In the standard computer architecture, data is stored in memory chips and data computing is executed in separate processor chips.

In contrast, in-memory computing is a new computing paradigm that seeks to perform both data storage and data computing in a memory network. Since this scheme can process a large amount of data stored within the memory network itself without having to move the data, and also because the data processing in the memory network is executed in a highly parallel manner, power consumption is substantially reduced. In-memory computing has thus emerged as one of the promising technologies to realize next-generation low-power AI semiconductor chips.

For this reason, research on in-memory computing has been intensely pursued worldwide. [...] By contrast, it has so far been difficult to use MRAM-another type of non-volatile memory-for in-memory computing despite MRAM's merits such as operation speed, endurance and large-scale production. This difficulty stems from the low resistance of MRAM, due to which MRAM cannot enjoy the power reduction advantage when used in the standard in-memory computing architecture.
