摘要： Improvements in the efficiency of two charge pump designs are presented. As a charge pump switches between modes, capacitances are charged. Due to charge sharing between capacitances, inefficiencies are introduced. Techniques for reducing these inefficiencies are presented for two different charge pump designs are presented. For a clock voltage doubler type of pump, a four phase clock scheme is introduced to pre-charge the output nodes of the pump's legs. For a pump design where a set of capacitances are connected in series to supply the output during the charging phase, one or more pre-charging phases are introduced after the reset phase, but before the charging phase. In this pre-charge phase, the bottom plate of a capacitor is set to the high voltage level prior to being connected to the top plate of the preceding capacitor in the series.

摘要： A charge pump system uses a dynamic switching approach, where the pump connections are independent of the load for each output. One large pump is designed to be shared between all of the outputs for use during the ramp up during recovery, with each output level also have one designated pump to maintain its level when under regulation. Each small pump is designed with capability that can maintain its output at its regulation level. Each of these pumps can be tailored to the corresponding output level, such as the number of stages being higher in the pump to supply the higher output level. The large pump unit is constructed to be ample to provide sufficient drive to be able to assist in the ramp up phase for all of the outputs and has as many switches needed to connect the pump with all the needed outputs.

摘要： Techniques and corresponding circuitry are presented for the detection of wordline leakage in a memory array. In an exemplary embodiment, a capacitive voltage divider is used to translate the high voltage drop to low voltage drop that can be compared with a reference voltage to determine the voltage drop due to leakage. An on-chip self calibration method can help assure the accuracy of this technique for detecting leakage limit.

摘要： A charge pump system can provide multiple regulated output levels, including several concurrently, in an arrangement that can reduce the area and power consumption of such a high voltage generation system. The charge pump system can be dynamically reconfigurable based on output requirements. When output level is low, but required for a large AC, DC load, the system is configured in parallel to share the load. When a higher output is required, such as for a programming in a non-volatile memory, the system is configured in serial to generate the desired high output level. The exemplary embodiment uses all of the pump units in each operation and, hence, is able to be optimized for smaller pump area and less power consumption, while still delivering the same pump ability as larger, more power consuming arrangements.
