Abstract

An integrated circuit for implementing reconfigurable logic, such as a field programmable gate array ('FPGA'), as described herein has multiple blocks of multi-ported memory. The memory has a plurality of read ports and a plurality of write ports. Each port of the multi-ported memory can be configured with a width and depth that is independent and separate from the width and depth of the other ports. The memory also includes a port for taking a synchronous snapshot of the contents of the memory or for loading the memory to an initial state. The memory shares routing lines used by a low level logic element thereby alleviating the need to add routing lines to an interconnect network just to satisfy the memory requirements.
