CONTROL/GATE AND BOOSTING CIRCUIT OF WORD LINE VOLTAGE

摘要

PROBLEM TO BE SOLVED: To provide a circuit and a semiconductor method which utilize capacitive coupling of a control/gate word line (a CG-WL). SOLUTION: In order to boost a control/gate voltage adjacent to a word line to be selected, capacitive coupling is utilized rather than generating a required boosting voltage through a decoder and a driver of a control/gate and a bit line. The voltage boosting method reduces the silicon region of an address/decoder, the degree of complexity of a decoder circuit is reduced, an address/decode/set-up time is reduced and no need is required to provide an excess voltage supply source for the address/decoder.
