Let’s face it: We’re addicted to SRAM. It’s big, it’s power-hungry, but it’s fast. And no matter how much we complain about it, we still use it. Because we don’t have anything better in the mainstream yet.
We’ve looked at attempts to improve conventional SRAM. We’ve looked at completely different memory technologies that might be in line to replace SRAM, like RRAM (first more than five years ago, then last year – and we’re still working on it) and MRAM. And, a couple of years ago, we looked at one attempt to create a new SRAM technology out of conventional transistors – to be clear, just one such transistor (instead of six), plus a possible select transistor.
The company was Zeno, and they were even leveraging this idea as a way to provide greater drive in a transistor – possibly meaning one could stick with older technologies for longer. But, back in the memory story, there was at least one unknown – granted, a “we think so,” but without proof.
