ADAPTIVE GRANULARITY ROW- BUFFER CACHE

According to an example, a method for adaptive-granularity row buffer (AG-RB) caching may include determining whether to cache data to a RB cache, and adjusting, by a processor or a memory side logic, an amount of the data to cache to the RB cache for different memory accesses, such as dynamic rando...

Summary:According to an example, a method for adaptive-granularity row buffer (AG-RB) caching may include determining whether to cache data to a RB cache, and adjusting, by a processor or a memory side logic, an amount of the data to cache to the RB cache for different memory accesses, such as dynamic random-access memory (DRAM) accesses. According to another example, an AG-RB cache apparatus may include a 3D stacked DRAM including a plurality of DRAM dies including one or more DRAM banks, and a logic die including a RB cache. The AG-RB cache apparatus may further include a processor die including a memory controller including a predictor module to determine whether to cache data to the RB cache, and to adjust an amount of the data to cache to the RB cache for different DRAM accesses.
