Abstract
A data transfer circuit includes data lines for transferring data, interface input/output blocks connected to the data lines for input or output of data through the data lines, and a leakage current monitor and compensate circuit connected to the data lines to detect and store magnitudes of leakage currents in the data lines before input or output of data, and generate and supply to the data lines compensation currents that compensate the leakage currents upon input or output of data. An example of the data line is a bit line of a memory, and an example of the interface input/output block is a memory cell.
