Abstract: In accordance with some embodiments, fuse information may be written into a fuse array in a way that provides sufficient redundancy, making it harder for malicious parties to attack the fuse array.

Abstract: In accordance with some embodiments, instead of providing replacement rows, an area within a fuse array may be reserved for storing addresses of bits that are defective. Then these bits can be readily repaired by simply reading the stored state of identified defective bit, and inverting the stored state of the identified defective bit to get the correct output.

Abstract: In one embodiment described herein, on-die programmable fuses may be used. On-die programmable fuses may be programmed by entities other than the chip manufacturer after the fuse array chip has been manufactured and shipped out. However, other non-volatile memories may also be used.

Abstract: In accordance with some embodiments, the way in which the fuses are sensed and, particularly, their order may be made more random so that it is much more difficult to simply exercise the device and determine all the values of the storage elements within the fuse array. One result is a more secure storage device.

Abstract: In accordance with some embodiments, multiple blind debug passwords are provided. Each of a plurality of interested entities may have its own password and each password may unlock a specific set of features offered by an integrated circuit. In some embodiments each entity does not know the other passwords of the other entities. Potentially interested entities include an integrated circuit end customer, the original equipment manufacturer, the entity that provided the features to the integrated circuit and a conditional access provider. All debug features may be controlled solely via access to the debug tiers which are accessed by multiple debug passwords. Lower tier passwords are required in order to access higher tiers. Debug features may be separated into multiple tiers with more intrusive access requiring multiple debug passwords in order to gain access.
Abstract translation: 根据一些实施例,提供多个盲调试密码。 多个感兴趣的实体中的每一个可以具有其自己的密码,并且每个密码可以解锁由集成电路提供的特定的一组特征。 在一些实施例中,每个实体不知道其他实体的其他密码。 潜在感兴趣的实体包括集成电路终端客户,原始设备制造商,为集成电路提供特性的实体和条件接收提供商。 所有调试功能都可以通过访问由多个调试密码访问的调试层来控制。 为了访问较高级别,需要较低级别的密码。 调试功能可以分为多个层次,更多的入侵访问需要多个调试密码才能访问。
