Briefly, the disclosure relates to circuits utilized to perform writing operations to a memory array, in which elements of the array comprise resistive memory cells coupled in series with an access device. In one embodiment, a circuit may comprise a supply voltage coupled to a first side of the array and a current source coupled to a second side of the array. The access devices of the elements of the array may be body-biased, which may operate to reduce the turn-on voltage (VTH) of the access devices. Particular voltages may be applied to gate regions of the access devices to control leakage current to the resistive memory cells of the array.
