Patent ID: 7057491

Claim:
A snake-like resistor network configuration having a first resistive element formed from a resistive material provided in a first layer of an integrated circuit, the first resistive element having a first end and a second end; the region between the first and second ends defining a normal conducting path along the configuration through which current will normally travel, the configuration being provided by a plurality of parallel rows, each row having a start portion and an end portion, the end portion of a first row being linkable to the start portion of a second row by means of a linking portion of same resistive material as that of the rows; a second resistive element, the second resistive element being linked to the first resistive element, thereby providing a compound resistor structure; the configuration further providing at least one node between the first and second ends, the at least one node being formed in a tab provided adjacent to the linking portion, the tab being formed of the resistive material, in the first layer, and extending outwardly and substantially perpendicularly from the normal conducting path and the node being remote from the normal conducting path; and a contact structure provided between said resistive elements and contacting the tab, the contact structure enabling programming of the configuration.
