Abstract
A weak signal detecting circuit in which a sensing circuit formed with a flip-flop circuit, and bit lines each having connected thereto a plurality of 1-transistor type memory cells, are interconnected by separation transistors for separating them from each other, and in which power supply transistors are inserted between power sources and the bit lines. When the power supply transistors are turned on, the separation transistors are turned off, so that a signal detection can be performed with little power consumption. Further, in such a case, the bit lines are disconnected from the sensing circuit to thereby enable a high-speed and highly sensitive detecting operation to be stably achieved regardless of the number of memory cells.
