Security data read-out protection method for IC with initiation of protection function by detecting current through conductive surfaces of IC upon application of given voltage |
摘要 |
The data read-out protection is effected using conductive surfaces (1) provided by the semiconductor chip which are connected in series, with measurement of the current flowing through the conductive surfaces upon application of a given voltage, for initiating a protection function for automatic erasure or over-writing of the security data. |
