Asked the seller but he doesn't know how it came.

The maximum theoretic addressable RAM registers are 4096, but the 41OS only support 1024 and only these registers can exist: status (16), main (320), extended (603)
The calculator is probably in a bad state, do a Memory Lost, then do a SIZE 000, then go into program mode, you should see 319 registers.
