... The device includes a 128 bit Protection Register and a Security Block to increase the protection of a system design. The Protection Register is divid- ed into two 64 bit segments, the first one contains a unique device number written by Numonyx, while the second one is one-time-programmable power supply by the user. The user programmable segment can PP be permanently protected ...
