Abstract
Certain aspects of the present disclosure provide methods and apparatus for generating a negative boost voltage for memory write operations. One example memory circuit generally includes at least one memory bank, a write circuit coupled to the at least one memory bank, and a boost generation circuit coupled to the write circuit. The boost generation circuit generally includes a first node coupled to a reference potential node of the write circuit; a second node; a first capacitive element having a first terminal coupled to the first node of the boost generation circuit; a first switch configured to selectively couple the first node to a reference potential node for the memory circuit; and a second switch configured to selectively couple a second terminal of the first capacitive element to the second node of the boost generation circuit.
