ABSTRACT:
Circuitry is provided that allows programmable memory regions to use the data input and output resources of nearby programmable logic regions. The regular width of the data input port of a programmable memory region can be effectively increased by selectively connecting the data inputs of one or more of the programmable logic regions to the memory region. Similarly, the regular width of the data output port of the programmable memory region can be effectively increased by selectively connecting the programmable memory region to the data outputs of one or more of the programmable logic regions.
