    摘要: A cigarette lighter that discourages humans from smoking which is to emit a prerecorded message each time the cigarette lighter is activated. A typical prerecorded message would be to warn the user that smoking is hazardous to one's health. The prerecorded message can be changed if such is desired.

    摘要: A precharge circuit for use in a static random access memory is disclosed two step bit line pair precharging scheme in a precharge cycle performed prior to a read operation. The first precharging step is performed via each drain-source path of N-channel MOS transistor pair to the corresponding bit lines in response to a first pulse generated by the write enable signal and the following second precharging step is performed via means for precharging more dominantly than the transistor pair in response to a second pulse generated by the address transition detection circuit. Owing to the off-state of the N-channel MOS transistor pair in a read operation after a write operation, high speed read operation is obtained.
