A method of configuring a random access memory matrix containing partially configured memories in the matrix. The method includes the steps of independently calculating a memory enable signal and a configuration signal for a partially configured memory in each memory tile of the memory matrix. Memory tiles not supported by a memory compiler are determined. A memory wrapper is provided for each tile not supported by the memory compiler. An address controller is inserted in the memory matrix for each tile in a group of tiles. Output signals from each memory location in a memory group having a common group index are combined into a single output signal. A first stripe of memory tiles containing non-configured memory having a first width is selected. A second strip of memory tiles containing configured memory having a second width is also selected.
