The sense amplifiers connected to the respective bitlines can remain inactive such that the sense amplifiers do not amplify the signals to storable signal levels. Then, when the wordline is set again to the inactive state, insufficient charge remains in the memory cells coupled to the wordline such that the data stored in memory cells coupled to the wordline are erased. These steps can be repeated using each of a remaining number of wordlines of all or a selected range of the DRAM array so as to erase the data stored in all of the DRAM array or a selected range.
Method for driving semiconductor device
It is an object to obtain a memory element (DRAM) storing multilevel data easily. The amount of charge accumulated in a capacitor of a memory element (DRAM) is controlled by changing the potential of a wiring (a bit line), which is used for writing data to the memory element (DRAM), in a period in which a transistor included in the memory element (DRAM) is on. Thus, multilevel data stored in the memory element (DRAM) can be obtained without a complex configuration of a semiconductor device including the memory element (DRAM).

Switch mode power converters using magnetically coupled galvanically isolated lead frame communication
An integrated circuit package for use in a switch mode power converter comprises an encapsulation and a lead frame. A portion of the lead frame is disposed within the encapsulation. The lead frame includes a first conductor having a first conductive loop disposed substantially within the encapsulation. The lead frame also includes a second conductor galvanically isolated from the first conductor.

A first control die including a first control circuit is coupled to the first conductor. A second control die including a second control circuit is coupled to the second conductor. One or more control signals are communicated between the first and second control dice through the communication link.

Control for fault-bypass of cascaded multi-level inverter
A cascaded multi-level inverter is controlled in fault bypass operation. Rather than relying on approximations or feedback forms, the reference voltages are generated as an analytic solution. The analytic solution and its implementation are not affected by the output frequency of the inverter and it is able to provide maximum possible balanced line-line voltage to a three-phase motor. In addition, the analytic solution provides exact limits for the allowable operation region of the motor power factor in order to prevent overvoltage conditions of the cell inverter.
