No one I know has any specific memories. (1.1.6)
This has an upside and a downside, we think. Upside: you wouldn't remember all the stupid stuff and regrets you had in life, like any of your awful haircuts. Downside: you wouldn't remember all the good stuff either. Is it worth it?

I eat the brain, and for about thirty seconds, I have memories. Flashes of parades, perfume, music... life. Then it fades, and I get up [...] feeling a little better. [...] A little less dead. (1.1.21)
R has to live vicariously through other people's memories of life. Because of this, he becomes a little addicted to memories. Maybe zombies don't have to eat brains to stay physically nourished, but they do if they want to be spiritually nourished.

"We have to remember everything. If we don't, by the time we grow up it'll be gone forever." (1.3.46)
Here, Julie doesn't make a distinction between good memories and bad ones. She says it's important to remember everything. But why? Well, in her universe, the alternative is being a zombie who remembers nothing, so we guess we'll grant her point.
