Here's the deal you can use playstation 1 memory cards on a playstation 2 but not vice versa.

No, the PlayStation 1 & 2 memory cards will not stop working.
Yes, but you cannot save playstation 1 games on a playstation 2 memory card as they are not compatible.
Memory cards are available for several game consoles, including the PlayStation Vita, PlayStation Portable (PSP), and Nintendo Switch. Additionally, older consoles like the PlayStation 1 and 2, as well as the Nintendo 64, also used proprietary memory cards for saving game data. The Xbox 360 and some earlier handheld devices like the Game Boy Advance also utilized memory cards for storage.
yes but only to play a ps1 game
You can play any Playstation One game without the use of a memory card. However, you will not be able to save your game. This goes for playing PSOne games on both the Playstation, Playstation 2, or a PSOne Classic on a PSP. (Though chances are since PSOne Classics can only be purchased over Playstation Network that you already have a memory stick to save onto.) If playing a PSOne Classic on a Playstation 3, you can save straight to the console's hard disc.
I do believe that a PlayStation 2 will recognize a PlayStation 1 memory card. I use a ps1 memory card in my ps2 might it might vary from the different memory card brands.
