DATA INVERSION CIRCUIT OF SEMICONDUCTOR DEVICE FOR PERFORMING INVERSION OPERATION BASED ON THE INTERVAL FOR READING DATA AND DATA INVERSION METHOD USING THE SAME

摘要

An integrated circuit device includes a data inversion circuit configured to support an inversion mode of operation. The inversion mode of operation inverts selected ones of a plurality of N-bit words received in consecutive sequence at inputs thereof. The data inversion circuit is further configured to support a bypass mode of operation. The bypass mode of operation disables inversion of a second one of the plurality of N-bit words when a delay between receipt of the second one of the plurality of N-bit words and receipt of an immediately preceding first one of the plurality of N-bit words is greater than a predetermined time interval. Related methods are also discussed.
