A system for simplifying the programmable memory-to-logic interface in field programmable gate arrays (FPGAs) is provided. An interface may be used to isolate the general purpose routing architecture for intra-programmable logic blocks (PLBs) from the random access memory (RAM) address lines, data lines, and control lines. The PLBs and the input-output resources of the FPGA access the embedded memory (or RAM) using dedicated direct interconnects. Certain of these direct interconnects may originate from PLBs in the vicinity of the RAM. The remainder run between the input-output (IO) pads/routing and the RAM blocks. A bus routing architecture is also provided to combine the memories to emulate larger RAM blocks. This bus routing provides interconnection among RAM blocks and is isolated from the PLB routing resources.
