Abstract

PURPOSE:To eliminate the generation of noise from an amplifier by a method wherein a gate circuit is provided between a memory cell array and an amplifier and have the array and the amplifier under connected condition by giving ''ON'' position to the circuit at the time of read-out only. CONSTITUTION:Word lines W1 and W2, etc. are crossed with bit lines B1 and B2, etc. and they are connected by transistors Q11, Q12, Q21 and Q22. Also, the current amplifier Am, which also works as the sense amplifier and provided in the memory cell array, is connected to the end section of the word line. Circuits are constituted as above, a read-out current is applied to the word line W1, etc., the current running on the bit line B1 for which the selected transistor Q11 is connected is amplified by the amplifier Am and it is led out as a current, and then a gate circuit G, which gives ''ON'' position between the array and the amplifier Am at the time of read-out only, is provided. As a result, no noise is sensed when a high voltage is applied for a charge pumping, etc. of the word line.
