Systems and methods pertain to a method of memory management. Gaps are unused portions of a physical memory in sections of the physical memory mapped to virtual addresses by entries of a translation look-aside buffer (TLB). Sizes and alignment of the sections in the physical memory may be based on the number of entries in the TLB, which leads to the gaps. One or more gaps identified in the physical memory are reclaimed or reused, where the one or more gaps are collected to form a dynamic buffer, by mapping physical addresses of the gaps to virtual addresses of the dynamic buffer.
