Title: Semiconductor memory device
Inventor: FUKUZUKURI YUKIO
IPC: G11C11/413
Filed: 1988-12-27
Abstract: PURPOSE:To prevent mis-latch and mis-output of output data by controlling the time of generation of an output buffer enable signal in response to the state of which of a memory cell of a redundant address or a normal address is accessed. CONSTITUTION:An output buffer control circuit 30 connects an input terminal of zero-side to an output terminal Y when the redundant enable signal phiR is zero. That is, at access to a normal memory cell (phiR=0), an output enable signal phiEN1 from an output control circuit 11 is connected directly to an output enable signal phiEN2 to an output buffer 10. On the other hand, at access to a redundancy memory cell (phiR=1), the output of a delay circuit 12 receiving the signal phiEN1 is connected to the signal phiEN2. Thus, in case of phiR=0, the time difference between the signals phiEN1 and phiEN2 is neglected and in the case of phiR=1, the time difference is caused only at a delay time of the delay circuit 12. In the case of normal and redundant memory access, the output data generation time and the time when the signal phiEN2 to the buffer 10 is logical 1 are coincident and a normal waveform is obtained at an external output DOUT.

Abstract: PURPOSE:To accomplish a monitor having a small sound or a sound close to a real one by changing the recovery time of an AGC circuit, the frequency characteristic of a recording amplifier and the gain of a microphone input circuit by interlocking with the switching of a pause circuit. CONSTITUTION:When a pause circuit changeover switch 18 is turned on, the recovery time changeover switch 19 of the AGC circuit, the output characteristic changeover switch 23 of the microphone input circuit and the frequency characteristic changeover switch 21 of the recording amplifier are switched from 1 2 by interlocking with turning on the switch 18. As a result, a resistor 20 for changeover is connected to the recording amplifier 4 in series, so that the recovery time is shortened and the amplifier 4 can follow the sudden change of the intensity of an input signal. Since the microphone input circuit is released from a state where a capacitor 16 and a resistor 17 are connected to an earth, the output level of the microphone input circuit is increased and the sound in the distance is made to be listened. Moreover, the clear monitoring sound close to an original sound is obtained.
