Google also shared that it is working on something called Tab Serializing for future updates. This tech is kind of like an improved version of Tab Discarding.
In Tab Serializing, Chrome will convert an open tab’s contents into binary, thus saving your current state of browsing that tab. It can then discard the tab in the same way that Tab Discarding works. However, when you later go to reload that tab, you are transported back to the state you were in last; you don’t have to start from scratch in that page.
