Description
(1)ホストがブロック内の1つまたはそれ以上のデータセクタを書き換える場合。このようなとき、このシステムは、消去されたブロックを更新用ブロックとして割り当て、書き換えられたデータは、更新用ブロックに書き込まれる。当初のブロック内の変化していないデータの一部または全部も更新用ブロックにコピーされ、その後同一の論理アドレスでのデータ要求の受信に応じて新たなブロックをアドレス指定するために、このシステム内に保持された論理アドレス−物理アドレス変換が更新される。ホストによるデータコピーまたはデータ書き換えによる更新用ブロックへのプログラミングが当初のブロックに記憶された全データに取って代わると、その後当初のブロックが消去される。
(2)特に当初のブロックが存在するプレーンにおいて、更新用ブロックとして割り当るために消去されたブロックが必要であるが、事前消去されたブロックが使用できない場合、2つまたはそれ以上の他のブロック内のデータが1つまたはそれ以上の他のブロックに整理統合される。次いで、それらの全データが移動された1つまたはそれ以上のブロックが消去され、現行プログラミング動作の更新用ブロックとして用いるのに使用可能となる。
(3)一実施形態では、更新用ブロックとするために必要な1つまたは複数のプレーン内のメタブロックの部分のみを整理統合することができる。残りのプレーン内のメタブロックの各ブロックは、残りのプレーン内の更新用ブロックが必要となった際に、要求に応じて後に整理統合することができる。
(4)さらに別の代替的な実施形態では、いくつかのプレーンでは整理統合が完了しているが、他はそうではないメタブロックは、ホストによって書き込みが行われ、かつ整理統合されたプレーン内の消去されたブロックを要求する。なんらかの所与のメタブロックのデータを完全に整理統合する(ガーベッジコレクションを行う)必要はなく、代わりに、要求に応じたブロックの整理統合および割り当てを可能にするために、各プレーン内のブロックが独立して管理される。この方法で、所与のメタブロックの他の部分から独立して、サブメタブロックをシステムの動作時に新たな物理アドレスに移動させることができる。
(1) セクタ0をはじめとして16セクタのホスト書き込み
(2) セクタ16をはじめとして8セクタのホスト書き込み
(3) セクタ24のホスト書き込み(1セクタのみ)
(4) セクタ25のホスト書き込み
(5) セクタ26のホスト書き込み
(6) セクタ27のホスト書き込み
(7) セクタ28のホスト書き込み
(8) セクタ29のホスト書き込み
(9) セクタ30のホスト書き込み、および
(10)セクタ31のホスト書き込み
本発明の種々の態様を例示的な実施形態に関して説明してきたが、本発明は添付の特許請求の範囲の全範囲内でその権利が保護されるべきことが理解できよう。
