Abstract

Embodiments of a memory, and calibration and operation methods thereof for reading data in memory cells are disclosed. In an example, an apparatus comprises transistors, and a charge sharing circuit coupled to the transistors through gate terminals of the transistors. The charge sharing circuit comprises a programmable electrical source, a first switch coupled to the programmable electrical source, a capacitor coupled to the first switch, and a second switch coupled to the capacitor, the first switch, and the gate terminals of the transistors. The programmable electrical source is configured to provide electrical charges to the capacitor when the first switch is turned on and the second switch is turned off. The capacitor is configured to provide at least a portion of the electrical charges to the gate terminals of the transistors when the first switch is turned off and the second switch is turned on.
