Abstract: A sensing circuit having a reduced bias clamp and method of operating the sensing circuit are provided. The sensing circuit may include a reference path and a sensing path. The sensing path may include a first transistor, clamping capacitor and a pair of switches. The reference path may include a second transistor, clamping capacitor and another pair of switches. A common gain stage receiving a bias voltage charges the clamping capacitors for the respective paths in a charging mode. The clamping capacitors may be charged in a serial or partially parallel manner during the charging mode. Each path may be coupled to a comparator, which may sense current or voltage changes between the paths during a sense mode. The sensing circuit may be configured to provide for sensing current or voltage changes between multiple sensing and/or reference paths in a parallel or serial manner.

Abstract: A sensing amplifier, coupled to at least one memory cell, includes an output terminal and a reference terminal, a multiplexer circuit, and a plurality of reference cells having equal value. An output terminal of the multiplexer circuit is coupled to the reference terminal of the sensing amplifier. Each of the reference cell is coupled to each input node of the multiplexer circuit. The multiplexer circuit is controlled by a control signal to select one of the reference cells as a selected reference cell to couple to the reference terminal of the sensing amplifier when each read operation to the at least one memory cell is performed. The plurality of reference cells are selected sequentially and repeatedly, and the one of the reference cells is selected for one read operation to the at least one memory cell.
