A last-level cache controller includes a system state monitor and a cache partitioning module. The system state monitor is configured to obtain a latency sensitivity factor, off-chip latency factors, and cache miss information for each of the processor cores. The cache partitioning module is configured to: obtain a first weighted latency according to the latency sensitivity factor, the off-chip latency factors and a first entry of the cache miss information that corresponds to a first cache partition configuration for each of the processor cores; obtain a first aggregated weighted latency according to the first weighted latency of each of the processor cores; determine whether a partition criterion is satisfied, where the partition criterion takes the first aggregated weighted latency into consideration; and partition the cache ways of the last-level cache using the first partition configuration when determining that the partition criterion is satisfied.

Method for managing a last level cache and apparatus utilizing the same

An operating method of a storage device is provided. The operating method comprises the following steps. First, a first data is read from a target address of a first storage unit. Then, an assisting unit checks whether the target address is corresponding to a second data stored in a second storage unit. If the target address is corresponding to the second data, the assisting unit updates the first data according to the second data to generate an updated data. Next, an Error Correction Code (ECC) performs a decoding process on the updated data to generate a decoded data.
