METHOD FOR PROVIDING NONVOLATILE STORAGE WRITE BANDWIDTH USING A CACHING NAMESPACE

摘要

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.

1. An apparatus for implementing an enhanced-write-bandwidth caching stream, the apparatus comprising:
a memory that stores machine instructions; and a processor that executes the machine instructions to apportion a first address space and a second address space comprising a logical namespace, subject the first address space to host-write throttling, exempt the second address space from host-write throttling when a second available space of memory cells currently available for programming associated with the second address space is greater than zero, and require 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.
