Some embodiments of the invention provide a configurable IC that includes several configurable computational tiles and several memory tiles. Each computational tile has a set of configurable logic circuits for configurably performing a plurality of computations and a set of configurable routing circuits. The routing circuits of the tiles configurably route signals between configurable logic circuits. Each memory tiles includes a set of routing circuits and a memory array for storing data on which the logic circuit perform computation. In this IC, at least a first memory tile has the same set of configurable routing circuits as at least a second computational tile.
