Title: Variable width management for a memory of a configurable IC

Abstract: Some embodiments of the invention provide a configurable integrated circuit ("IC"). The IC includes several non-configurable memories for storing and outputting data. The IC also includes several configurable logic circuits that each can configurably perform a set of functions, and several configurable interconnect circuits that each can configurably perform a set of connection operations. The IC further includes several multiplexers, each multiplexer having input, output, and select terminal sets. During the operation of the IC, at least a first multiplexer's input terminal set receives the output of a first memory from a set of configurable interconnect circuits, while the select terminal set receives a set of select signals from at least one configurable logic circuit that direct the multiplexer to output a sub-set of the first memory's output data along the first multiplexer's output terminal set.
