Circuitry for facilitating the use of the memory elements in the look-up tables (“LUTs”) of a field programmable gate array (“FPGA”) as user-accessible, distributed RAM. For example, a register associated with a LUT and that is not needed in the read data path in user RAM mode can be used to...http://www.google.fr/patents/US7391236?utm_source=gb-gplus-shareBrevet US7391236 - Distributed memory in field-programmable gate array integrated circuit devices
