ABSTRACT:
Various apparatuses and methods in which a sense amplifier circuit couples to a current source to provide current for the sense amplifier circuit and also couples to one or more memory cells to sense a charge being stored by each memory cell. Store protection circuitry reduces a voltage potential across critical nodes of the sense amplifier circuit to a difference between a store voltage and Vdd when the store voltage is about to be applied to any of the one or more memory cells. The store protection circuitry connects Vdd to one or more of the critical nodes of the sense amplifier circuit when the store voltage is about to be applied to any of the one or more memory cells.
