Memory management for WiFi Media Access Control (MAC) frames includes dividing a memory into equally-sized smaller chunks; writing a MAC frame that is larger in size than one-chunk size into several chunks; appending special information to each chunk to specify whether the chunk is a starting chunk or an intermediate chunk of the MAC frame or whether the chuck is currently unoccupied at all; linking the chunks carrying the MAC frame; and specifying a task waiting to be performed for the MAC frame. The several chunks may be noncontiguous or contiguous. The memory management technique may further comprise searching the memory for chunks comprising frames waiting for a certain task. The memory management technique may further comprise marking the chunks as empty after the certain task is completed.
