Current leakage reduction

摘要

This description relates to a circuit including a bit line. The circuit further includes at least one memory bank. The at least one memory bank includes at least one memory cell, a first device configured to provide a current path between the bit line and the at least one memory cell when the at least one memory cell is activated, and a second device configured to reduce current leakage between the bit line and the at least one memory cell when the at least one memory cell is deactivated. The circuit further includes a tracking device configured to receive a mirror current substantially equal to a current along the current path, the tracking device configured to have a resistance substantially equal to a cumulative resistance of all memory cells of the at least one memory cell.
