Rapid equalizing ground line and sense circuit

摘要

A rapid equalizing ground line and sense circuit. The ground line Circuit includes a reference transistor and a plurality of switching circuits. When the ground line signal is disabled, corresponding ground line of the switching circuit couples with the pre-charging bus to initiate a pre-charging operation. If the selected ground line signal is enabled, the selected switching circuit initiates a data sensing operation. If the selected ground line signal is disabled, the corresponding ground line of non-selected switching circuits continues to pre-charge. When the selected ground line signal changes from an enable state to a disable state, the corresponding ground line of the selected switching circuit and corresponding ground line of the non-selected switching circuit are coupled to a voltage source.
