A semiconductor memory such as a flash memory having addressable sectors of stored data with access to the stored data being controlled by control logic includes a register coupled to the control logic and having bits corresponding to data sectors to be protected and a protection code indicating that access to the identified sectors is to be controlled. The supporting means may be a stand, which may also contain at least one-foot holder and an arm bar. The fluid is contacted with the ionic liquid for take-up of the fluid by the ionic liquid.
