Description
図1は、本発明の第1の実施形態に係るNAND型フラッシュメモリ(以下、メモリとする。)の構成を示す断面図である。また、図2は、図1のメモリの平面図である。このNAND型フラッシュメモリは、樹脂等からなるパッケージ1の内部に、複数のメモリチップ2が積層されて構成されている。ここで、積層されたメモリチップ2を上から順にChip1、Chip2、Chip3、Chip4と定義する。積層されたすべてのメモリチップ2の平面方向中心には、それぞれメモリチップ2の外部と信号の授受を行うパッド3が形成されている。また、積層されたメモリチップ2が各々有するパッド3は、メモリチップ2の最下層から最上層までを縦断的に貫通する複数の貫通ビア4によって共通接続されている。
(1)コマンドCom入力は、チップイネーブル信号/CE及びコマンドラッチイネーブル信号CLEがそれぞれ“L”,“H”の状態で、ライトイネーブル信号/WEのトグルが入力されると、データI/O0〜7は、入出力バッファ16を介してコマンドとしてコマンドバッファ19に格納され、制御回路20に出力される。
(2)アドレスAdd入力は、チップイネーブル信号/CE及びアドレスラッチイネーブルALEがそれぞれ“L”,“H”の状態で、ライトイネーブル/WEのトグルが入力されると、データI/O0〜7が入出力バッファ16を介してアドレスとしてアドレスバッファ17に格納される。
(3)データ入力は、チップイネーブル信号/CE、コマンドラッチイネーブル信号CLE及びアドレスラッチイネーブル信号ALEがそれぞれ“L”,“L”,“L”の状態で、ライトイネーブル信号/WEのトグルが入力されると、データI/O0〜7が取り込まれることにより行われる。このデータI/O0〜7は、書き込みモードならば入出力バッファ16を介して入力データとしてセンスアンプ15に出力される。また、メモリチップ内部に設けられたタイマーの周期や電圧などの各種設定データを変更するパラメータセットモードでは、このデータI/O0〜7は、制御回路内部の各種設定データ用のラッチに格納される。
(4)読み出しは、チップイネーブル信号/CE及びリードイネーブル/REが “L,L”の状態で、メモリセルアレイ13に記憶されたデータが入出力バッファ16を介しI/O0−7に出力されることにより行われる。
本発明の第2の実施形態に係るメモリについて説明する。なお、全体の構成要素については図1〜図3に示す第1の実施形態と同一構成であるためその説明を省略する。図9は、第2の実施形態に係るメモリのパッド3の構成の詳細、及びパッド3と各メモリチップ2の内部回路との間の接続関係の詳細を示すブロック図である。
本発明の第3の実施形態に係るメモリについて説明する。図11は、第3の実施形態に係るメモリの最上層のメモリチップ2Bを示す平面図である。なお、断面図は、第1の実施形態(図1)と同様に示されるのでその図を省略する。
図14は、本発明の第4の実施形態に係るメモリの構成を示す断面図である。また、図15は、このメモリの最上層のメモリチップを示す平面図である。
