Vpplとは 意味・読み方・使い方

Voltage difference between VPPL and VARY is assumed to constant, and adjusted higher than a threshold value of MOS constituting the pre-charge circuit, and voltage difference between VPPH and VARY is assumed to constant, and adjusted higher than a threshold value of MOS constituting a memory cell.例文帳に追加

ＶＰＰＬとＶＡＲＹとの電圧差は一定とし、プリチャージ回路を構成するＭＯＳのしきい値より高く調整し、ＶＰＰＨとＶＡＲＹとの電圧差は一定とし、メモリセルを構成するＭＯＳのしきい値より高く調整する。 - 特許庁

By a voltage changeover circuit 14, a first boost voltage (VPP) is supplied to the main word driver 12 in a predetermined area to which the selected main word line MWL belongs, among a plurality of areas divided from a memory cell array, while in areas other than the area, a second boost voltage (VPPL) lower than the first boost voltage is supplied to the main word driver 12.例文帳に追加

電圧切り替え回路１４は、メモリセルアレイを分割した複数の領域のうち、選択されたメインワード線ＭＷＬが属する所定領域では第１の昇圧電圧（ＶＰＰ）を、それ以外の領域では第１の昇圧電圧より低い第２の昇圧電圧（ＶＰＰＬ）を、メインワードドライバ１２に供給する。 - 特許庁
