Abstract
A memory device has an array of memory cells. A column decoder is configured to address the memory cells. A charge-pump supply circuit generates a boosted supply voltage for the column decoder. A connecting stage is arranged between the supply circuit and the column decoder. The connecting stage switches between a high-impedance state and a low-impedance state, and is configured to switch into the high-impedance state in given operating conditions of the memory device, in particular during a reading step.
