Abstract

The invention concerns a computer device (8) which comprises at least two memory units (10, 12). The memory units (10, 12) are of the kind the function of which in the computer device at least partly is determined by whether electric connection is the case between two contact surfaces (14, 16; 18, 20) of the memory unit (10, 12). The computer device (8) also comprises a switching device (22). The switching device (22) is connected with the two contact surfaces (14, 16) of at least a first (10) of the memory units (10, 12). The electric connection between the two contact surfaces (14, 16) of the first memory unit (10) may be opened and closed with the switching device (22). The function of the first memory unit (10) is thus determined by whether the switching device (22) is set for closure of opening of the connection between the contact surfaces (14, 16).
