Abstract:
The present disclosure relates to reference and sense architecture in a cross-point memory. An apparatus may include a memory controller configured to select a target memory cell for a memory access operation. The memory controller includes word line (WL) switch circuitry configured to select a global WL (GWL) and a local WL (LWL) associated with the target memory cell; bit line (BL) switch circuitry configured to select a global BL (GBL) and a local BL (LBL) associated with the target memory cell; and sense circuitry including a first sense circuitry capacitance and a second sense circuitry capacitance, the sense circuitry configured to precharge the selected GWL, the LWL and the first sense circuitry capacitance to a WL bias voltage WLVDM, produce a reference voltage (VREF) utilizing charge on the selected GWL and charge on the first sense circuitry capacitance and determine a state of the target memory cell based, at least in part, on VREF and a detected memory cell voltage VLWL.
