Programmable logic device incorporating function blocks operable as wide-shallow RAM

摘要

An integrated circuit capable of efficiently storing data words of varying length is disclosed. The inventive integrated circuit can be a programmable logic device that includes a plurality of configurable memory array blocks. The integrated circuit includes a control circuit that characterizes data to be stored and based upon that characterization provides control signals to direct connectors. The direct connectors then directly connect selected configurable memory array blocks when a single memory array block could not accommodate the data to be stored.
