A remote control unit radiates signals of operated program selection keys (3) via an infrared transmitter circuit (10, 11, 12). In order to simplify the selection of one of several TV programs for the user, the remote control device has a receiver circuit (18 to 23). The latter detects picture signals of the TV programs to be selected via program selection keys (3). A storage unit stores these pic...

Modified CAMs are used to generate a reset signal to other redundant CAMs which provide decoding for accessing redundant memory. Because the redundant CAMs use a single UPROM, half-latch circuit, the redundant CAMs are capable of latching to the wrong logic state. Whenever signal conditions which can cause improper latch-up are present, at least one of the modified CAMs are affected due to their s...

A semiconductor memory device is described in which wordline redundancy is implemented without impacting the access time. A redundant decoder circuit generates a wordline drive inhibit signal which inhibits the generation of a normal wordline signal. Deselection also deselects the normally accessed reference cells, requiring that the redundant cells provide their own reference signal. This last re...

A data communication apparatus having an error retransmission mode allows the operator to ascertain an amount of error data when an error is contained in data and when the error is not corrected despite retransmission of the error a predetermined number of times, or makes it possible to reproduce data with respect to correctly received data by discriminating correct data contained in error data, t...
