A computer system comprises a memory controller and a synchronous non-volatile memory device coupled to the memory controller via a main memory bus. The priorities of multiple CAM array blocks within the CAM device may be programmed before or as entries are loaded therein and may be reprogrammed during operation as the allocation of entries within the CAM device changes. The lever mates to a fixed handle portion to complete a handle for facilitating handling of the canister. The comparator circuit compares a test result of a circuit-under-test with an expected value. The solid detergents are also in the form of a solid, homogeneous, self-sustaining body for improved handling and use. To support use in logarithmically compressing the current generated by a photodiode, an adaptive bias signal can provided which maintains an essentially constant bias on the photodiode’s internal junction.
