Abstract
Description
追加の層を形成することによりメモリスタックを形成することが可能であり、この場合、追加される層のそれぞれは、追加のパーティションコンポーネントによって分離され、これにより高密度メモリデバイスを与えるように、複数のスタックがパラレルに形成され得る。選択的導電性媒体は、有機導電層と1又はそれ以上のパッシブ層とを有するメモリ構造の様々な部分に形成される。選択的導電媒体は、求められるインピーダンス状態をメモリセル内にプログラムするバイアス電圧を印加することによってプログラムされ(例えば、ライトされ)る。
この求められるインピーダンス状態は、1又はそれ以上のビット情報を表し、求められるインピーダンス状態を保持するために継続的な電源供給あるいはリフレッシュサイクルを要請しない。選択的導電媒体のインピーダンス状態は、電流を印加することによって、又、選択的導電媒体のインピーダンスを読み取ることによってリードされる。ライトされたインピーダンスと同様に、リードされたインピーダンス状態は1又はそれ以上のビット情報を表わす。加えて、有機メモリデバイス及びセルを製造する方法、有機メモリデバイス及びセルを使用する方法、及び有機メモリデバイス及びセルを含むコンピュータのようなデバイスも与えられる。
