Abstract

UN CARTUCHO DE MEMORIA CONFORME A ESTA INVENCION SE INSTALA EN FORMA QUE PUEDA EXTRAERSE EN UN DISPOSITIVO DE PROCESAMIENTO D TAL COMO UNA MAQUINA PORTATIL DE JUEGOS ELECTRONICOS CONTENIENDO UNA CPU (UNIDAD CENTRAL DE PROCESO), Y CONTIENE UNA ROM (PROM DE CONMUTACION DE BANCOS, Y UNA RAM (MEMORIA DE ACCESO ALEATORIO) EXTERNA SE CONTIENE EN EL CIRCUITO DE CONMUTACION DE BANCOS. LA RAM TIENE COMO RESERVA UNA CELULA. LOS DATOS CLAVE PRIMERO Y SEGUNDO SE ESCRIBEN PEVIAMENTE DENTRO DE LA PROM. CUANDO EL SUMINISTRO DE ENERGIA SE CONECTA, SE DA SALIDA A UNA SEÑAL DE REINICIALIZACION CUANDO EL VOLTAJE DE FUENTE DE ALIMENTACION ALCANZA UN VALOR DADO. CUANDO SE LEE EL PRIMER DATO CLAVE DE LA PROM, Y TAMBIEN SE DA SALIDA A UNA SEÑAL DE REINICIALIZACION, LA ROM EXTERNA SE HACE ACCESIBLE POR LA CPU. CUANDO, Y DESPUES DE LEER EL SEGUNDO DATO CLAVE DE LA PROM, SE PROHIBE EL ACCESO POR LA CPU A LA RAM EXTERNA.
