USB flash drives generally don't have good lifetime unless they are industry graded, so I would not trust them as only backup option for storing bitcoin keys.

There is one interesting new drive Blaustahl USB, that is based on FRAM (Ferroelectric RAM) that could last up to 200 years, but it can only store 8kb of data, that means only text files.
It is expected that future firmware updates are going to include encryption for better security.

But I remember, if you go just want to run a bitcoin wallet on a pen drive then it's possible as long as the wallet is lite just like Electrum.

Since you mentioned Electrum, this software wallet has a portable version that you can put on a USB flash drive and run it from there or move it across various devices with that USB. But that's again different from what OP is asking about. Being an SPV client, Electrum doesn't require that you download the entire blockchain, which significantly shortens the sync times before you can use it.

So for that we need to create blockchain supported pen drive or memory card first or need another more things ?

A pen drive or a flash drive has a limited storage. Just as Pmalek stated, if you're going to create a blockchain for supporting that pen drive you like to have, the storage that it has got won't be enough to store the entire thing there. So, probably you're confused about seed phrases, private keys or seeds being stored on them whether as a file or simply in a notepad. Soon, pendrives are going to be a thing in the past, we're now even seeing external hard drives only for back ups that are serving the same as flash drives. But I remember, if you go just want to run a bitcoin wallet on a pen drive then it's possible as long as the wallet is lite just like Electrum. I haven't done it though about the launcher of there being saved but sure you can save the installer on a pen drive or memory card as long as it has enough storage.

Bitcoin is data and that data can go on anything that it is run on at the time. As technology advances we can get chips that go on our finger tips, and yes, your blockchain data can go on it and you can access your keys using them. Drives and memory cards were always used as means of accessing the blockchain, but there are easier and safer ways to do that now.

You have the freedom to use your bitcoin as you like.

The real question you wanted to ask is not whether you can store bitcoin on a USB flash drive, but whether you can run a node from it. Don't forget that the blockchain is quite big and it will always get bigger. So, your first obstacle is storage. Compared to SSDs, USB flash drives have slower read and write speeds. It's going to become a nightmare to download, store, and verify blocks on a USB stick. I don't think pen drives could handle that load. The load will also increase the chances that the USB flash drive breaks or causes the data on it to become corrupted.

I would advice against it.

The thing is your cryptocurrency let me cut it down to Bitcoin is not stored on any device rather it is stored on blockchain, what the device holds is the seed phrase or private key that gives you access to the coins on the blockchain. If you have either of this things then you have ownership of the coins on their addresses

Now can the seedphrase or private key be stored on pen drives and memory cards, yes they can but it is mostly not advisable though. You can also store a wallet entire file on them

(just a curiosity)
Technology is always updated day by day.
Will it be possible to store crypto between pen drives and memory cards in the near future?

Just like @Zaguru12 mentioned, let me explain further. Your Bitcoins aren't actually stored in your wallet, but on the Blockchain. The wallet is simply a software or hardware tool that helps you manage your keys and connect to the Blockchain. It allows you to send or receive Bitcoin using your public key. When you check your wallet balance, you're seeing the total amount of Bitcoin assigned to the addresses linked to your private keys on the blockchain. So, owning a wallet means you have a tool to view and manage your Bitcoin holdings.

Regarding storing Bitcoin on flash drives or memory cards, as Zaguru12 also pointed out, you can only store your keys or wallet data files there. However, it's risky because these devices can get damaged, and if your keys are lost, they may be unrecoverable.
