Abstract
A semiconductor memory apparatus may include a memory cell, a write driver, and a voltage adjustment circuit. The write driver may provide the memory cell with a program current based on a write data. The voltage adjustment circuit may adjust a voltage level of a global word line coupled to the memory cell when a current flowing through the memory cell or the voltage level of the global word line is greater than a threshold value.
