Abstract

An open block management apparatus, system, and method for non-volatile memory devices is disclosed herein, providing improved performance for namespace-based host applications. The namespace identifier is applied to determine the open blocks to which to direct data from storage commands. One benefit of the disclosed technique is fewer de-fragmentation operations and more efficient memory garbage collection. Another benefit is the ability to secure private allocations of physical memory without needing to assign a partition or implement hardware isolation.
