    Abstract: Method and apparatus for managing data in a memory, such as a flash memory array. In accordance with some embodiments, a memory cell is provided with a plurality of available programming states to accommodate multi-level cell (MLC) programming. A control circuit stores a single bit logical value to the memory cell using single level cell (SLC) programming to provide a first read margin between first and second available programming states. The control circuit subsequently stores a single bit logical value to the memory cell using virtual multi-level cell (VMLC) programming to provide a larger, second read margin between the first available programming state and a third available programming state.

    Abstract: A microactuator, for example for a disc drive, comprising a substrate, a sandwich structure on the substrate, and a passivation layer over the substrate and the sandwich structure. The sandwich structure has a bottom electrode formed from noble metal, a piezoelectric layer, and a top electrode formed from noble metal. The microactuator further has one or both of a bottom adhesion layer present between the bottom electrode and the passivation layer, and a top adhesion layer present between the top electrode and the passivation layer. That is, the microactuator may have only the bottom adhesion layer, only the top adhesion layer, or both the bottom adhesion layer and the top adhesion layer.
