Abstract
A memory system includes a first wiring, a second wiring, a memory cell between the first and second wirings, a first power supply line configured to supply a first voltage, a first transistor between the first power supply line and the first wiring, and configured to supply a current necessary to perform a write operation to the memory cell, a second transistor arranged between the first power supply line and the first wiring, and connected in parallel with the first transistor, a second power supply line configured to supply a second voltage to the second wiring corresponding to the memory cell unselected in the write operation, and a first current copy circuit configured to copy a current flowing to the second power supply line from the second wiring corresponding to the memory cell unselected in the write operation, and configured to control the second transistor based on a copied current.
