can I take a memory out of my iPad?

Your iPad display is broken - and without a functioning display, you cannot unlock or interact with the iPad.

As described, your iPad requires repair - however, unless you have a pre-existing iCloud or iTunes backup of the iPad, your locally stored data has been irretrievably lost.

Yes, the data is irretrievable.

So as to ensure security of your data, iOS/iPadOS employs an encrypted file system. The only copy of the encryption key, that is required to decrypt the data, is securely stored in device security chip (the “secure enclave”). Entering your device passcode unlocks the security chip and releases the encryption key to the Operating System - which in turn decrypts your data.

As you cannot interact with the broken iPad, you cannot input your Passcode; without a Passcode, the encryption keys remain locked away; without the encryption keys, data cannot be decrypted - and therefore remains irretrievable.

No.

The memory configuration is fixed for the life of the device. You can neither add, nor remove, internal RAM or storage.

If the iPad is broken, no data can be recovered from the encrypted filesystem. Unless you have a pre-existing iCloud or iTunes backup, any locally stored data has been irretrievably lost.
