    • A ferroelectric film measuring device and a measuring method therefor, which are capable of measuring the transient current with high accuracy produced during the polarization reversal of a ferroelectric capacitor having a very small capacity. A pulse producer (10) produces a pulse signal, which is applied to the upper electrode (62) of a ferroelectric capacitor through a transmission line and a tip (50). The output current (iFE) from a lower electrode (64) produced at pulse application is converted into a voltage (V1) by a resistance element (30), amplified by a preamplifier (40), and delivered, the current (iFE) being measured on the basis of the output voltage (V0). A pulse having negative and positive amplitudes is applied to the upper electrode (62) continuously twice each time and the output current produced at each pulse application is measured. And the difference between the currents corresponding to the first and second pulses is found, thereby making it possible to eliminate the influences of charge current due to parasitic capacity such as in the transmission line, to extract only the polarization current due to polarization reversal of the ferroelectric substance, and to measure the properties of the ferroelectric film with high accuracy.

    • A circuit and method provide isolated modulation of SRAM bitline voltage levels for improved voltage bump retention testing of the SRAM cells. A first FET is connected to Vcc, bitline load gates of the SRAM cell, and test mode operation control logic. A second FET is connected to the bitline load gates, the test mode logic, and an external pin of the SRAM device. During test mode operation, the first FET disables Vcc to the bitlines, and the second FET enables the internal bitline voltage levels to be modulated by a voltage supply received through the external pin of the device. Modulation of the bitline voltage levels is isolated from normal operating voltage levels of peripheral circuitry such as the wordlines. An alternate embodiment provides a CMOS transmission gate in place of the second FET.
