Abstract

A random access memory circuit adapted for use in a field programmable gate array integrated circuit device is disclosed. The FPGA has a programmable array with logic modules and routing interconnects programmably coupleable to the logic modules and the RAM circuit. The RAM circuit has three ports: a first readable port, a second readable port, and a writeable port. The read ports may be programmably synchronous or asynchronous and have a programmably bypassable output pipeline register. The RAM circuit is especially well adapted for implementing register files. A novel interconnect method is also described.
