发明名称 Data security device for protecting stored data
摘要 A security device (10) for protecting sensitive data stored in a resettable memory (110) includes a housing (11) formed of six ceramic plates (P1-P6) each having provided thereon a pair of thin film conductive path segments arranged in a meandering configuration. The thin film conductive path segments are joined together by interconnection devices (30) each including a pair of ceramic studs (e.g. K9, K10) having conductive areas (34, 38) thereon connected by an interconnect block (e.g. N5), thereby forming two complete thin film conductive paths (WMA, WMB) which meander in a closely spaced, parallel manner over the entire inner surface of the housing (11). Interrupting or short circuiting the thin film conductive paths (WMA, WMB) causes reset means (130) to reset the resettable memory (110) thereby erasing the data stored therein.
