Title: Circuit for repairing defective semiconductor memory device
Inventor: CHO SONG-HUI
IPC: H01L27/00
Filed: 1992-10-06
Granted: 1995-11-02
Abstract: The circuit consists of a cell array connected to output unit through bit lines, a memory cell array and redundancy cell array formed by separating word lines, a low predecoder for generating word line operating signals, a low decoder and redundancy low decoder which selectively operates word lines of the memory cell array and redundancy cell array, and a redundancy address decoder activating the low decoder or redundancy low decoder by comparing external addresses and the programmed addresses.

Title: Automatic gain control device and its method of modem
Inventor: LEE JAE-KON
IPC: H04L27/02
Filed: 1992-11-13
Granted: 1995-04-17
Abstract: The device having a gain controlling device for amplifying a receiving signal into a gain corresponding to the predetermined gain control value and a digital converter for digital-converting the gain-controlled signal to thereby apply it to the receiving part, is provided further including: first and second energy detectors for detecting the level of the output data of the digital converter at every level detecting section each set differently with each other to compare it with the previously set high-level threshold value/low-level threshold value, and applying the gain control value corresponding to the comparing value to the gain controller; a switch for selectively applying the output data of the digital converter to the first and second energy detectors by a predetermined control; and a mode detector for detecting an operation mode from the output data of the digital converter and controlling the switching operation of the switch in response to the detected operation mode.
