Load pump type of voltage generator circuit |
摘要 |
Disclosed is a load pump type of voltage generator circuit designed to produce several levels of voltage higher than a supply voltage of the circuit. The circuit comprises two cascades of elementary pumping cells. Each cell is controlled by at least one driving signal. To make the two cascades work together, it is planned to modify the driving signal or one of the driving signals assigned to the last cell of the first cascade in such a way that the first cascade delivers a voltage equal to the sum of the voltages delivered by the two cascades. In a particular embodiment, the two cascades comprise the same number of cells and can work in parallel. Application to the field of non-volatile memories for the production of read and write voltages.
