Patent 7577814 was granted and assigned to American Megatrends on August, 2009 by the United States Patent and Trademark Office.
A firmware memory manager allocates memory for code and data based on a lifespan associated with each allocation. The memory manager determines whether each allocated block of memory is needed only for a certain lifespan. Based on this determination, blocks of memory needed beyond the certain lifespan are all allocated adjacent to each other in memory. Once execution exceeds the certain lifespan, memory needed only for boot time is reported as being available for reuse by an operating system.
