In simpler terms, the SRAM density improved by 2.9% (according to ChatGPT). Which is better than it sounds, because SRAM had reached a wall, in terms of density gains, and, chips can be dominated by SRAM in terms of surface area, so this can mean a lot more room for logic, even though that is also getting considerably denser.

  There's some hope of smaller SRAM in the future - <a href="https://raaam-tech.com/technology/" rel="nofollow">https://raaam-tech.com/technology/ is a three-transistor SRAM.

    It's not quite SRAM, it needs to be refreshed like DRAM. That's the main downside compared to SRAM but it's still very interesting.

    Yes, the density vs power tradeoff could make a lot of sense in a few applications.
