We analyzed memory writes in detail, finding that, on average, the PRAM main
memory writes about 80MB to the memory side, but half of the write operations are
memory allocation operations, as shown in Figure 20. The dual-buffer model reduces
write operations of dynamic data to the main memory. Our proposed model not only
reduced write counts of dynamic data, but also changed the method of execution of
static data, thus resulting in decreased write operations to the main memory
