Abstract
Disclosed is a current sense amplifier suitable for a nonvolatile memory device such as a magnetic random access memory. In the current sense amplifier, a reference memory cell for sensing is implemented by a memory cell equal to a normal memory cell without fabricating different reference memory cells. The current sense amplifier is formed of first and second cross coupled differential amplifiers being covalent bonded. The current sense amplifier compares a current flowing to a sensing node of a memory cell directly with currents flowing to reference sensing nodes.
