Description
そこで、RAMセルのメモリー素子をサイリスタ素子に変えることでリフレシュ動作とプリチャージタイムにかかる時間を省き、また、S−RAMよりもクロス配線等のRAMセルの配線を簡素化することができる。
Claims (1)
- 現在のCPUのボトルネックを発見した為、このボトルネックを修正して改良した時の為に、CPUのメモリーへのアクセス・スピードをさらに速くする様に改良したRAMセル。
サイリスタと、第1のトランジスタと、第2のトランジスタと、第3のトランジスタとを有し、前記サイリスタのアノードはサイリスタに電流を供給する第1の配線、I線に接続され、前記サイリスタのゲートは前記第1のトランジスタのソース又はドレインの一方に接続され、前記サイリスタのカソードは、前記第2のトランジスタのソース又はドレインの一方、及び前記第3のトランジスタのソース又はドレインの一方に接続され、前記第1のトランジスタのソース又はドレインの他方は、書き込み用の第2の配線、W線に接続され、前記第1のトランジスタのゲートは読み出しと書き込みに用いる第3の配線、R/W線に接続され、前記第2のトランジスタのソース又はドレインの他方は接地電位と接続され、前記第2のトランジスタのゲートは前記第2のトランジスタのソース又はドレインの他方に接続され、接地電位とし、前記第3のトランジスタのソース又はドレインの他方は、読み出し用の第4の配線、D線に接続され、前記第3のトランジスタのゲートは、前記第3の配線、R/W線に接続されることを特徴とするRAMセル。
