Abstract

The present disclosure relates to a memory cell, a memory array, and methods for writing a memory cell. In an example embodiment, a memory cell comprises a first transistor, a second transistor, and a differential sense amplifier. The first transistor is a Vt-modifiable n-channel transistor and the second transistor is a Vt-modifiable p-channel transistor, each transistor having first and second main electrodes. The first main electrodes of the first and second transistors are connected together. The differential sense amplifier is connected to the second main electrodes of the first and the second transistor. The differential sense amplifier is adapted for sensing the current difference between the first transistor and the second transistor.
