Samsung has been developing a new in-memory computing system for months that uses memory technology. MRAM chips (Magnetoresistive Random Access Memory). It is an improved version of DRAM modules that allow data to be stored and processed in the same component. Now the company has confirmed the first demonstration and the intention to mass produce this new architecture.
The MRAM architecture offers multiple advantages. Among them, and according to Samsung, the possibility of store the data from the memory network itself, something that allows avoiding the use of external storage components. Also process data in parallel from the same chip, which can reduce power consumption. All this, in addition, taking into account that the MRAM memory is a non-volatile memory. That is, you can store the data even when the device is turned off.
One of the drawbacks of MRAM memories, according to Samsung, is their low resistance. This prevents taking advantage of the power reduction when running on a standard computing architecture. In this case, the Samsung researchers decided to tackle this problem by devising a new MRAM matrix chip intended for AI computing.
By introducing MRAM, memory that has already reached commercial-scale production integrated into system semiconductor manufacturing, into the realm of in-memory computing, this work expands the frontier of next-generation low-power AI chip technologies. generation.
Explains Samsung.
In the tests, published by the review Nature and carried out together with Samsung Advanced Institute of Technology (SAIT) and Samsung Electronics Foundry, the company managed to achieve 98% accuracy in handwritten digit classification and up to 93% accuracy in face detection in scenes.
Samsung continues to work on its LPDDR5 DRAM memory
MRAM memories represent an important advance for Samsung. However, the company continues to develop its system LPDDR5 DRAM with up to 64GB per module, which offer up to 1.3 times higher processing performance than the LPDDR5 architecture.
This new RAM memory module will allow Samsung to offer sufficient performance to process artificial intelligence tasks and it is thought to be able to process all the information that the metaverse will require. On the other hand, and as confirmed the company, its use may go beyond mobile phones.
