Hybrid MRAM array structure and operation |
摘要 |
This invention relates to MRAM technology and new variations on MRAM array architecture to incorporate certain advantages from both cross-point and 1T-1MTJ architectures. The fast read-time and higher signal-to-noise ratio of the 1T-1MTJ architecture and the higher packing density of the cross-point architecture are both exploited by combining certain characteristics of these layouts. A single access transistor 16 is used to read the multiple MRAM cells in a segment of a column, which can be stacked vertically above one another in a plurality of MRAM array layers arranged in a "Z" axis direction.
