Three-Dimensional Magnetic Recording Device

Multilevel and Three‐Dimensional Nanomagnetic Recording

“…As mentioned above, previous research has identified the multilevel mode as a likely form of 3D recording to impact the future world of memory and storage applications [37][38][39]. In this mode, a varying recording field was used to sequentially record across the media thickness, as illustrated in Figure 6.6a.…”

Multilevel 3 Bit-per-cell Magnetic Random Access Memory Concepts and Their Associated Control Circuit Architectures

“…In multi-level memory, the conventional two states (1 bit) within a single memory cell are replaced by structures capable of storing data in 4, 6 or even 8 states, potentially tripling the density of the memory [12][13][14][15][16][17][18][19][20].…”
