Abstract
An apparatus for implementing an enhanced-write-bandwidth caching stream includes a memory that stores machine instructions and a processor that executes the machine instructions. The apparatus apportions a first address space and a second address space that comprises a logical namespace. The apparatus also subjects the first address space to host-write throttling, and exempts the second address space from host-write throttling. The apparatus further requires that valid data in memory cells corresponding to the second address space be invalidated at an interval not to exceed a number of host writes equaling the capacity of the second address space.
