Abstract: Methods, systems, and devices for flexible information compression at a memory system are described. For example, a memory system may compress information in a change log to reduce the frequency of transfers of one or more mappings between volatile memory and non-volatile memory. The memory system may compress information associated with a sequence of sequentially-indexed addresses by storing the information associated with those addresses at a pair of entries in the change log. The memory system may additionally switch between a first operating mode associated with identifying sequentially-indexed addresses and generating compressed entries, and a second operating mode associated with generating entries of the change log for each address received in commands.

Abstract: Tantalum powders produced using a tantalum fiber precursor are described. The tantalum fiber precursor is chopped or cut into short lengths having a uniform fiber thickness and favorable aspect ratio. The chopped fibers are formed into a primary powder having a controlled size and shape, narrow/tight particle size distribution, and low impurity level. The primary powder is then agglomerated into an agglomerated powder displaying suitable flowability and pressability such that pellets with good structural integrity and unifrom pellet porosity are manufacturable. The pellet is sintered and anodized to a desired formation voltage. The thusly created capacitor anode has a dual morphology or dual porosity provided by a primary porosity of the individual tantalum fibers making up the primary powder and a larger secondary porosity formed between the primary powders agglomerated into the agglomerated powder.
