This abstract first appeared for US patent application 18479960 titled 'SEMICONDUCTOR SYSTEM FOR INPUTTING AND OUTPUTTING DATA

Original Abstract Submitted

A data input and output circuit includes a data input circuit configured to precharge first and second input and output lines after the end of a power-up operation and configured to generate first and second input data by driving the first and second input and output lines from each of which transfer data having a set logic level, among first and second transfer data, are output after the start of a write operation. The data input and output circuit also includes a data output circuit configured to generate first and second internal data based on logic levels of the first and second input data.
