Abstract

Disclosed herein are related to a memory cell including one or more programmable resistors and a control transistor. In one aspect, a programmable resistor includes a gate structure and one or more source/drain structures for forming a transistor. A resistance of the programmable resistor may be set by applying a voltage to the gate structure, while the control transistor is enabled. Data stored by the programmable resistor can be read by sensing current through the programmable resistor, while the control transistor is disabled. In one aspect, the one or more programmable resistors and the control transistor are implemented by same type of components, allowing the memory cell to be formed in a compact manner through a simplified the fabrication process.
