Abstract:
An apparatus for measuring the transfer characteristics of a charge transfer device and the charge holding capability of a capacitor wherein said charge transfer device and said capacitor are integral to a memory cell, the apparatus comprising:a memory array consisting of a plurality of said memory cells arranged in a matrix formation, wherein at least one of said memory cells is coupled to a bitline and to a wordline; a circuit having two inputs, wherein by applying a constant voltage to the first input of said circuit and by applying a voltage pulse to the second input of said circuit, electrical charge is transferred via a corresponding bitline coupled to the capacitor of said at least one memory cell when a corresponding wordline coupled to said at least one memory cell is activated; and a voltage amplifier for amplifying the voltage in said capacitor and for enabling a transfer of said amplified voltage to a means for performing an analog measurement.
