    摘要： An improved memory circuit having a fast write speed is disclosed. A first control signal is generated when a first period of time has elapsed from the initiation of an access cycle, in a fixed timing both in a read operation and a write operation. A second control signal for enabling a data input circuit when a second shorter period has elapsed from the initiation of the access cycle only in a write operation. A data transfer between a selected bit line and a bus line is performed when at least one of the first and second control signals.
