Title:
SEMICONDUCTOR MEMORY, CONTROL METHOD FOR OUTPUT SIGNAL IN SEMICONDUCTOR DEVICE, AND OUTPUT SIGNAL CONTROL CIRCUIT
Document Type and Number:
Japanese Patent JP3762558
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To surely prevent erroneously sensing data due to the occurrence of an output noise by variation of power source voltage, when a sense amplifier performs data-sensing.
SOLUTION: This device is provided with a signal delay means 100 that makes an output control signal/OE of an external input inputted from the outside not to be transmitted to an output buffer 6 for a prescribed period after change of an address, in the prescribed period after an address AD is changed, malfunctions caused by occurrence of an output noise, while the sense amplifier 1 performs data-sensing is prevented by preventing inversion of a logic level of a signal 'OUT' outputted from the output buffer 6, when the sense amplifier 1 performs data-sensing.
