Title:
メモリ装置のワード線信号をブーストするブーストシステムおよびブースト方法
Document Type and Number:
Japanese Patent JP4178205
Kind Code:
B2
Abstract:
System for boosting a signal for use in a memory device. The system includes a circuit for providing a boosted signal used to produce a word line signal in a memory device. The circuit includes a pre-charge stage that has an output terminal and is coupled to receive an address signal and a boost control signal. The pre-charge stage is operable to produce the boosted signal having a pre-charged level at the output terminal. The circuit also includes a boost stage that is coupled to receive the boost control signal and produce a boost activation signal at a boost stage output terminal that is coupled to the output terminal via a capacitive element. When the boost activation signal is active, the boosted signal is set to a selected boost level that is independent of supply voltage.
