Abstract

A memory device includes a memory array, a reference voltage generator and a driver circuit. The memory array includes a memory cell. The reference voltage generator is configured to generate a reference voltage based on a threshold voltage of a select transistor of the memory cell. The driver circuit is coupled to the reference voltage generator and is configured to generate at least one of a bit line voltage and a word line voltage according to the reference voltage, wherein the memory cell is driven by the at least one of the bit line voltage or the word line voltage, and the reference voltage generator comprises a resistor that is configured to sense the threshold voltage of the select transistor through a current flowing through the resistor.
