Abstract
PURPOSE:To stabilize a memory cell and to cause a reading speed to be high without almost increasing energy consumption by causing a constant current source to be high current only when a switching is executed from the selection of a line to non-selection and causing the rising of the line to be a high speed. CONSTITUTION:The current of a constant current source IBB for base driving is switched by a line driving signal and an inverter circuit is driven. When the base of this inverter circuit is driven from a high electric potential to a low electric potential, a transistor is temporarily turned off by the time constant of capacity connected to an emitter and the constant current source and the base current of a constant current circuit, which is composed of transistors Qw12-Qwm2 and resistances R12-Rm2, is switched to the high current at a high speed only at the switching time of the line. Thus, the high current is flown only when it is needed and without almost increasing the energy consumption, the memory cell is stabilized and the high reading speed is realized.
