Abstract
A nonvolatile memory device includes an array of magnetic memory cells, and control logic circuit having a voltage generator therein, which is configured to generate a gate voltage. A row decoder is provided, which is connected by word lines to the array of magnetic memory cells, and has a word line driver driven therein, which is responsive to the gate voltage. A column decoder is provided, which is connected by bit lines and source lines to the array of magnetic memory cells. A write driver is provided, which has a write voltage generating circuit therein that is configured to output a write voltage, in response to: (i) a reference voltage generated using a replica magnetic memory cell, and (ii) a feedback voltage generated using a magnetic memory cell in which a write operation is to be performed.
