IPC: G01S13/76
Filed: 1986-07-21
Abstract: PURPOSE:To remove an unnecessary non-synchronous signal such as a fruit response signal or random noise without damaging a normal response signal, by comparing an arrival receiving signal with a previous receiving signal by plural cycles from said receiving signal and taking the majority of said receiving signals. CONSTITUTION:A receiving signal is branched into two to be inputted to a majority logic circuit 5 through a circuit wherein shift registers 3, 4 for transferring one of the branched signals on the basis of a shift clock pulse to delay the repeated cycle of a question signal by one cycle are connected in series, and the other branched receiving signal and a part of the output of the shift register 3 are respectively inputted to the input terminal of the majority logic circuit 5 to obtain a normal signal from the output terminal of the majority logic circuit 5. Since signal discrimination is performed on the basis of the majority decision of the signal during reception and the signal previous by several cycles, a non-synchronous signal such as a fruit response signal can be excluded by simple circuit constitution without lacking the normal signal.

Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory which is reducible in cost by having its chip size suppressed when it is formed of the same silicon as a logic part. SOLUTION: A compressing and restoring device which compresses write data and also restore read data is built in the memory.
