Magnetic random access memory designs with controlled magnetic switching mechanism |
摘要 |
An MRAM array is formed of MTJ cells shaped so as to have their narrowest dimension at the middle of the cell. A preferred embodiment forms the cell into the shape of a kidney or a peanut. Such a shape provides each cell with an artificial nucleation site at the narrowest dimension, where an applied switching field can switch the magnetization of the cell in manner that is both efficient and uniform across the array.
