Abstract:
A non-volatile memory device includes a feedback circuit and a precharge switching transistor. The feedback circuit generates a feedback signal based on a voltage level of a bitline during a precharge operation. The precharge switching transistor, in response to the feedback signal, controls a precharge current for precharging the bitline. The speed of the precharge operation may be increased and/or mismatch of the bias signals in precharging a plurality of bitlines may be reduced.
Abstract:
A flash memory device controls a common source line voltage and performs a program verify method. A plurality of memory cells is connected between a bit line and the common source line. A data input/output circuit is connected to the bit line and is configured to store data to be programmed in a selected memory cell of the plurality of memory cells. The data input/output circuit maintains data to be programmed within the data input/output circuit during a program verify operation, and decreases noise in the common source line by selectively precharging the bit line based on the data to be programmed.

Abstract:
To check insulation of a pouch electric cell, probes are contacted to an electrode of a pouch electric cell and an aluminum layer of a pouch of the pouch electric cell, respectively, and then an electric characteristic value between the probes is measured. The probe contacted with the aluminum layer has a contact portion made of conductive elastic material. Also, insulation of the pouch electric cell is determined by comparing the measured electric characteristic value with a reference value. Thus, physical characteristics of an outer periphery of a flexible pouch may be sufficiently exhibited in measuring or checking insulation of a pouch electric cell such as insulation resistance, thereby improving reliability of electric contact and minimizing physical damage or deformation of the pouch electric cell.

An apparatus for checking insulation of a cell module assembly composed of a plurality of pouch cells includes a first probing unit electrically contacted to an electrode of the cell module assembly; a second probing unit electrically contacted to aluminum films of selected ones of the pouch cells in the cell module assembly; and a measuring unit for measuring an insulation resistance between the first probing unit and the second probing unit. This apparatus may measure insulation resistances of a plurality of pouch cells of the cell module assembly at once, thereby ensuring faster insulation checking.
