Abstract: An apparatus (10) for intelligent programmable sensing using elements mounted on a silicon base comprise a silicon sensor transducer (12) and a configurable analog signal conditioner (16). A configurable memory (18) is part of signal conditioner (16) and stores conditioning instructions to direct configurable analog signal conditioner operations. A configurable memory (24) is part of configurable analog-to-digital converter (24) and stores converting instruction to direct configurable analog-to-digital converter operation. Digital signal processor (28) processes digitized signals (26) from configurable analog-to-digital converter (24). A program memory (30) stores program instructions for processor (28) to generate results (32). Configuration and results bus (34) directs communications within the sensor (10) and through communications interface (36).

Abstract: A magnetic memory system is provided that includes magnetic domain data chips having a block replicate organization wherein the system may include data chips having one or more defective minor loops. A dedicated minor loop is provided on the chip to store a redundancy map for locating the defective minor loops. The dedicated minor loop also provides for storing a synchronization pattern for initializing the system by having each minor loop properly addressed for transferring magnetic domains. The dedicated loop can only be accessed by a separate swap pin preventing a write operation by the user thus preserving the data stored therein.
