An example of a method reads a spin torque transfer (STT) memory cell, and writes the STT memory cell using information obtained during the reading of the STT memory cell to set a pulse to write the STT memory cell. An example of an apparatus includes a STT memory cell and read/write circuitry coupled to the STT memory cell to determine a read current (IREAD) through the STT memory cell and to set a pulse to write the STT memory cell using IREAD. Additional embodiments are disclosed.
