Programmable logic device with multi-port memory

An integrated circuit comprising:

• a plurality of logic circuits, each of said logic circuits carrying signals and including a plurality of logic elements;
• each of said logic elements having a plurality of input lines and at least one output line;
• an interconnect network which routes signals between said logic elements of one of said logic circuits and out of said logic circuit;
• and
• a plurality of memory blocks associated with said logic circuits, said memory blocks storing and outputting certain of the signals, wherein each of said memory blocks uses said input lines or said output lines of said logic elements to route signals to or from said memory block so that said memory block shares a portion of said interconnect network with said logic elements.
