摘要： The present invention is an controller for dynamically allocating RAM between powersave code copied from ROM and transient RAM memory used for storing packets. When the utilization of the transient RAM memory is low, code segments are copied from ROM and executed from RAM using a RAM pointer table which is updated after the code segments are copied over from ROM, and when the utilization of the transient RAM memory is high, code segments are deallocated from RAM and the pointer table is updated to point to the corresponding location in flash ROM.
