Abstract: Disclosed is the serial access memory having the improved precharging system of reading bit lines (4). In this serial access memory, an address pointer (9, 114) outputs a signal for selecting one of the reading bit lines (4). Meanwhile, each reading bit line (4) is provided with an MOS transistor (7) for precharging the same. By using the output of the address pointer (9, 114) to control on/off of the MOS transistor (7), the period when each reading bit line (4) is precharged is limited within the period when the reading bit line is selected. As a result, current flowing through the reading bit lines (4) during the data reading can be reduced to achieve the reduction in power consumption of the serial access memory and the increase in the operation speed.

Abstract: A semiconductor integrated circuit according to the present invention has a series circuit of a first field effect transistor and a load which is connected between a first potential point and a second potential point. The first field effect transistor operates in response to a control signal inputted in a gate thereof, whereby a high-level or low-level output signal is extracted from a node between the first field effect transistor and the load to output terminal. A second field effect transistor is also connected between the output terminal and the first potential point. Thus, when a surge causing the first field effect transistor to break down is applied to the output terminal, the second field effect transistor conducts to pass a surge current, whereby the first field effect transistor is prevented from being broken down.
