SENSE AMPLIFIER CIRCUIT

PROBLEM TO BE SOLVED: To obtain a sense amplifier circuit free from read errors due to the power supply noise. SOLUTION: A clock generator circuit 14 outputs a transfer gate control signal after receiving an output ENABLE signal from a DELAY circuit 12. Upon receipt of the transfer gate control signal from the clock generator circuit 14 a sense amplifier 15 turns off the transfer gate. Upon receipt of the output ENABLE signal from an address input-ATD circuit 11-DELAY circuit 12 an output buffer 13 controls the data output according to this ENABLE signal. If the turn off of the transfer gate is effected during the time for which the output power noise is being produced, the power noise influence can be suppressed. Thus, it is possible to avoid a read error due to the influence of the output power noise of the sense amplifier.
