Not having enough memory is pushing chip architecture backwards — and it still will not be enough afterwards.

Patrick Moorhead founded the semiconductor analysis firm Moor Insights & Strategy. On August 18 he posted what he had heard from at least a dozen chip design companies on one question, all of them telling him the same three things. They are changing and accelerating future architectures to use less memory, or less sophisticated memory. They expect those designs to reach volume in three to five years. And they acknowledge that even with the new architectures there still will not be enough memory (the post, 08-18). This matters as the backdrop to main line item 3. The constraint on modern AI keeps drifting away from arithmetic and toward the speed of getting data next to the compute — and the Cerebras approach of skipping external memory entirely and growing it on the wafer is one bet on exactly that constraint. ⚠️ Take the discount in full: this is an analyst relaying private conversations, naming no company, offering no numbers, and falsifiable by nobody, from a firm with commercial relationships across the chip industry. What it is good for is direction and time scale, not fact.
