Description
本特許出願は、その各々が該出願の譲受人に与えられ、その各々が参照によりその全体が本明細書に明確に組み込まれる、2016年8月31日に出願の名称が“Hybrid
Memory Device”であるRyanによる米国特許出願番号15/252,886の優先権を主張する2017年8月21日出願の名称が“Hybrid Memory Device”である国際特許出願番号PCT/US2017/047787の優先権を主張する。
RAM(DRAM)、同期型ダイナミックRAM(SDRAM)、強誘電体RAM(FeRAM)、磁気RAM(MRAM)、抵抗変化RAM(RRAM)、及びフラッシュメモリ等を含む様々な種類のメモリデバイスが存在する。メモリデバイスは揮発性又は不揮発性であり得る。不揮発性メモリ、例えば、フラッシュメモリは、外部電源が存在しなくても長時間、データを蓄積できる。揮発性メモリデバイス、例えば、DRAMは、外部電源により定期的にリフレッシュされない限り、それらの蓄積状態を時間と共に喪失し得る。バイナリメモリデバイスは、例えば、充電又は放電されるコンデンサを含み得る。充電されたコンデンサは、しかしながら、リーク電流を通じて時間と共に放電され得、蓄積された情報の喪失をもたらす。定期的なリフレッシュなしにデータを蓄積する能力等の不揮発性の機構が利点であり得る一方で、揮発性メモリの幾つかの機構は、しかしながら、より高速な読み出し又は書き込み速度等の性能の利点を提供し得る。
キャッシュは、メモリデバイスの単一の行、メモリバンク毎の行、又は様々な行/列の組み合わせの形式をとり得る。
ステン等)、金属合金、導電性金属化合物、導電的にドープされた半導体、又はその他の導電性材料等で作られてもよい。図1の例に従うと、メモリセル105の各行は単一のワード線110に接続され、メモリセル105の各列は単一のデジット線115に接続される。1つのワード線110及び1つのデジット線115を活性化する(例えば、ワード線110又はデジット線115に電圧を印加する)ことによって、それらの交点で単一のメモリセル105がアクセスされ得る。メモリセル105にアクセスすることは、メモリセル105を読み出す又は書き込むことを含み得る。ワード線110とデジット線115との交点は、メモリセルのアドレスと称され得る。
することなく交換され得る。回路200は、選択コンポーネント220及びリファレンス信号225をも含む。図2の例では、セルプレート230はプレート線210を介してアクセスされ得、セル底部215はデジット線115-aを介してアクセスされ得る。他の場合、プレート線210は存在しなくてもよい。例えば、常誘電体材料を有するDRAMメモリセルは、デジット線115-aのみで動作され得る。上述したように、コンデンサ205を充電又は放電することによって様々な状態が蓄積され得る。
ス(例えば、リファレンス信号225の電圧)とその後比較され得る。
0に到達するまで経路330に従う。電荷状態305及び310は、残留分極(Pr)値、すなわち、外部のバイアス(例えば、電圧)を除去すると残留する分極(及びしたがって、電荷)とも称され得る。抗電圧は、電荷(又は分極)がゼロである電圧である。
ば、悪意のある攻撃は、セルがその耐久限界に達するまで連続して読み出し動作を実施することによって、FeRAMセル105-bの破壊を試み得る。FeRAMセル105-b中に蓄積されたデータをキャッシュすることは、その破壊を阻止し得る。例えば、メモリアレイ100-aは、強誘電体コンデンサを有し得るメモリセル105-bに対する読み出しリクエストを受信し得、メモリセル105-b中に蓄積されたデータを、常誘電体コンデンサを含む第2のメモリセル(例えば、メモリセル105-c)へ転送し得、ここで、該データは、メモリセル105-bの読み出しリクエストを受信することに基づいて、メモリセル105-bからメモリセル105-cへ転送される。メモリセル105-cは、直接接続、又は他のコンポーネント若しくはデバイスを含む回路経路を介してメモリセル105-bと電子通信し得る。メモリセル105はメモリコントローラ140と各々電子通信し得る。データを転送することは、メモリセル105-b中に蓄積された論理値を読み出すことと、該論理値をメモリセル105-cに書き込むこととを含み得る。
バンクへのアクセスの試みに基づいて、カウンタはインクリメントされてもよく、タイマは操作されてもよい。
、したがって、高密度の強誘電体メモリセルを有し得、強誘電体メモリセル105-b及びDRAMセル105-cの両方を同じ基板405上に形成するために、DRAMアレイに使用される既存の形成プロセスが使用されてもよい。
bの寿命を保持するために、DRAMセルは、メモリアレイ100-bに対するキャッシュとして使用され得る。DRAMキャッシュ及びメモリアレイ100-bは同じ基板又はダイ上に設置され得る。
しなければならない電源を必要とする。同じ基板405-a上にFeRAMアレイ100-cとDRAMアレイ100-dとを有する上で論じた例では、それらの転送は、高速且つオンチップであり、電力需要を2つの方法で削減する。
0を堆積することによって、第2の導電材料がその後形成され得る。電極材料730はコンデンサの第2の電極であり得る。処理ステップ703において、マスク材料720は、以前にマスクされた凹部を露出するために除去され得る。
ンサを含む該第1のメモリアレイを基板上に形成することと、第2のメモリアレイであって、複数のピラーを含む該第2のメモリアレイを基板上に形成することであって、ここで、複数のピラーの内の各々は強誘電体コンデンサを含むことを含み得る。
ータの流れをも管理し得る。BIOSコンポーネント1015は、リードオンリーメモリ(ROM)、フラッシュメモリ、又は任意のその他の不揮発性メモリ中に蓄積されたプログラム又はソフトウェアを含み得る。
受信することを含み得る。幾つかの例では、ブロック1105の動作は、図1、図6、図9、及び図10を参照しながら記述したようなメモリコントローラ140により実施され得、又は容易にされ得る。
モリセルの読み出しの試みを第4のメモリセルへ向けるための手段とを更に含み得る。幾つかの場合、第1のメモリセルは複数の強誘電体メモリセルを含み、第2のメモリセルは複数の常誘電体メモリセルを含む。
、アクセス動作の数をカウントするための手段と、アクセス動作の数が閾値を超えると判定するための手段とを含む。幾つかの場合、第1のメモリセルのアクセス動作の数が閾値を超えると判定することは、アクセス動作の割合が閾値割合を超えると判定するための手段を含む。
タイプは不揮発性メモリセルを含む。
することを含み得る。幾つかの例では、凹んだ常誘電体コンデンサは、基板中の凹部を含み、ここで、アレイの各凹部の開口部の最大寸法は100ナノメートルよりも小さい。
ロボルト(0V)の電圧に保持されるがグランドと直接接続されない電気回路のノードを指す。したがって、事実上のグランドの電圧は、一時的に変動し得、定常状態で約0Vに
戻り得る。事実上のグランドは、オペアンプ及び抵抗を含む電圧分圧器等の様々な電子回路素子を使用して実装され得る。その他の実装も可能である。“事実上グランドする(virtual grounding)”又は“事実上グランドされる(virtuallygrounded)”は約0Vに接続されることを意味する。
