Abstract:The main memory access latency has not much improved for more than two decades. Approximate memory is a technique to reduce the DRAM access latency in return of losing data integrity, and it is beneficial for applications that are robust to noisy data. To obtain reasonable outputs from applications on approximate memory, it is crucial to protect critical data while accelerating accesses to non-critical data. A fundamental limitation of approximate memory is that the approximation granularity, the minimum size … Show more
