Patent number: 7274283Abstract: Methods and apparatus that allow restricted access to internal registers of an integrated circuit (IC) device via an interface are provided. Unrestricted access to internal registers via the interface may be allowed during a manufacturing process to allow device testing. After such testing is complete, the device may be placed in a restricted access mode, for example, by blowing a master “lock” fuse, to prevent unrestricted access to one or more of the internal registers via the interface. However, full or partial access to the internal registers may still be provided via an access code or “combination lock” allowing the master fuse lock, in effect, to be bypassed.Type: GrantFiled: April 29, 2004Date of Patent: September 25, 2007Assignee: International Business Machines CorporationInventors: Paul Stewart Yosim, Irfan Rashid
