Abstract (en)
[origin: WO2006071402A1] An embedded circuit (14) in a memory device (10) is used in place of an external test device to perform time-consuming tasks such as voltage verification during the setting of reference cells (20). An external test device (16) programs at least one reference cell (22) to a predetermined value. The embedded circuit uses the cell (22) programmed by the external device as a comparative reference to program additional reference cells (20).
