My experience, having dealt with depression for a couple of decades now is that yes, it definetly has affected my memory. Some memory loss due to stress, some due to depression itself, some to effects of suicide attempts/lack of oxygen, some maybe even due to ADD or things like that. Spelling a big problem, like others here have said, I used to be very good at spelling and had a better vocabulary.

As I say to myself, I know I have memory problems, I just can't remember exactly what they are. I forget people, I forget names, my longer term memory is better than my short term. But my memories surrounding particularly emotional events or severly depressed or stressed times in my life are worse, I think, than other times.

I get the impression that my memories - at least some of them - are in boxes and don't come out unless a certain emotion or some other kind of trigger brings them to my mind. It's frustrating and embarrassing for me.
