"Large language models, the AI tech behind things like Chat GPT, are 
 just what their name implies: big. They often have billions of 
 individual computational nodes and huge numbers of connections 
 among them. All of that means lots of trips back and forth to 
 memory and a whole lot of power use to make that happen. And the 
 problem is likely to get worse.
 
 One way to potentially avoid this is to mix memory and processing. 
 Both IBM and Intel have made chips that equip individual neurons 
 with all the memory they need to perform their functions. An 
 alternative is to perform operations in memory, an approach that 
 has been demonstrated with phase-change memory.
 
 Now, IBM has followed up on its earlier demonstration by building a 
 phase-change chip that's much closer to a functional AI processor. 
 In a paper released on Wednesday by Nature, the company shows that 
 its hardware can perform speech recognition with reasonable 
 accuracy and a much lower energy footprint." ...
