Can i save my data from sd card formatted as internal memory but now pc says format memory card
No... You have factory reset the device which deleted the unlock key that would have given you any hope of recovering this data. The data was encrypted and unlock code was stored on the device, which you factory reset and erased everything. Your SD card was "internal storage" which was erased, the fact it was removed from the device isn't relevant because even technically the data is there it isn't recoverable by any means.
