摘要:
A configuration and method for low-loss writing of an MRAM includes setting voltages at bit lines and word lines such that the voltage across the memory cells between a selected word/bit line and the individual bit line/word lines is minimal. A voltage drop occurs on a selected word/bit line connected to a particular memory cell when writing into the memory cell and voltages at the bit/word lines are set to minimize a cell voltage across the memory cells between a selected word/bit line and individual bit/word lines. A voltage drop occurs on a selected word/bit line connected to a particular memory cell when writing into the particular cell, and, when a voltage V1 and a voltage V2
