Abstract
PURPOSE:To shorten the read time by supplying not only currents passing first and second transistors TRs but also the current passing a third TR in the read operation where the bit line potential goes to the high level. CONSTITUTION:A power supply terminal is connected to a node N2 through a third P-channel TR Q9 whose a signal E is inputted to gate. When a sense amplifier 4 is switched to the operatable state and a TR Q6 is set to the conductive state and a TR Q8 is set to the nonconductive state, the TR Q9 is made conductive because the signal E given as the gate input becomes active, namely, goes to the low level. Consequently, not only the current is supplied to the node N2 from a power source VCC through TRs Q6 and Q7 but also the current is supplied to the node N2 through the TR Q9, and the potential of the node N2 is raised more quickly. Thus, the read speed is increased because the output potential of the sense amplifier is determined more quickly.
