Abstract
A semiconductor memory device has adjacent memory arrays and isolation transistors disposed between a common bit sense amplifier and the memory arrays. An isolation control circuit according the present invention generates the power supply voltage Vcc (not the boost voltage Vpp) during the burn-in mode of operation, so that the gate oxide layer of the isolation transistors is prevented from being destroyed or deteriorated.
