Free version of the research paper: https://arxiv.org/abs/2503.19544v1 The memory cell is huge in comparison with semiconductor memories, but it is very fast, with a 40 GHz read/write speed. There are important applications for a very high speed small memory, e.g. for digital signal processing in radars and other such devices, but this will never replace a general-purpose computer memory, where much higher bit densities are needed.

From the paper > footprint of 330 × 290 µm2 using the GlobalFoundries 45SPCLO That’s a 45nm process but the units for the chip size probably should have been 330um? However I’m not well versed enough in the details to parse it out. https://arxiv.org/abs/2503.19544
