You cannot make DRAM on the same process with competitive, high-end logic, and they want to embed a lot of buffers on chip to reduce communication power use, so SRAM is the only game in town.
- skavi 6y agoIntel had eDRAM (Crystal Well) for a while as the cache for their integrated Iris graphics.
- etaioinshrdlu 6y agoFrom wikichip: The eDRAM silicon die is separate from the main Haswell die but is packaged together with it.
- skavi 6y agoHuh, I should have done more reading.
- Tuna-Fish 6y agoCrystal Well was only eDRAM in the marketing sense. There have been other, actual eDRAM technologies that can be manufactured on some logic processes, however none of them are compatible with the state of the art TSMC 7nm logic process.
