    • A programmable metallization device comprises a first electrode and a second electrode, and a first dielectric layer, a second dielectric layer, and an ion-supplying layer in series between the first and second electrodes. In operation, a conductive bridge is formed or destructed in the first dielectric layer to represent a data value. During read, a read bias is applied that is sufficient to cause formation of a transient bridge in the second dielectric layer, and make a conductive path through the cell if the bridge is present in the first dielectric layer. If the bridge is not present in the first dielectric layer during the read, then the conductive path is not formed. Upon removal of the read bias voltage any the conductive bridge formed in the second dielectric layer is destructed while the conductive bridge in the corresponding other first dielectric layer, if any, remains.
    • 可编程金属化器件包括第一电极和第二电极,以及在第一和第二电极之间串联的第一电介质层,第二电介质层和离子供给层。 在操作中,在第一电介质层中形成或破坏导电桥以表示数据值。 在读取期间,施加足以在第二电介质层中形成瞬态电桥的读取偏压,并且如果桥存在于第一介电层中,则形成通过电池的导电路径。 如果在读取期间桥不在第一电介质层中,则不形成导电路径。 在去除读取的偏置电压时,形成在第二介电层中的任何导电桥被破坏,而相应的其它第一介电层(如果有的话)中的导电桥保留。
