Abstract

LAS MEMORIAS TIPO FLASH PUEDEN DESCRIBIRSE EN FORMA "BYTE" O "WORD", PERO NO SE EXTINGUEN EN BLOQUE. CADA BLOQUE DE UNA MEMORIA FLASH DISPONE DE UNA DURACION DE TIEMPO LIMITADA CON RESPECTO A LOS CICLOS DE ESCRITURA/EXTINCION EJECUTABLES. UTILIZACION DE UN ALGORITMO DE OPTIMIZACION. UN GRADO DE RELLENO DE LOS BLOQUES INDIVIDUALES DE LA MEMORIA FLASH SE DETERMINA Y CONSIGUE DE FORMA CORRESPONDIENTE EL GRADO DE RELLENO DE UN DESPLAZAMIENTO DE DATOS EN EL EXTREMO DE MEMORIA O SE DETERMINA DE TAL MODO, QUE SE EXTINGUE UN BLOQUE, O DE FORMA QUE PUEDA SER COPIADO DENTRO DE LA MEMORIA EN LA ZONA LIBRE DE LOS BLOQUE, O QUE LOS DATOS PUEDAN SER ALMACENADOS DE FORMA INTERMEDIA PARA LA EXTINCION DE LAS ZONAS MARCADAS Y DESPUES DE LA EXTINCION DE LOS BLOQUES PUEDEN SER RECONSTRUIDOS DE NUEVO O BIEN QUE LOS DATOS SEAN TRANSMITIDOS SOBRE ZONAS MARCADAS DE EXTINCION POR MEDIO DE UNA DISPOSICION DE UNION.
