Abstract: A computer system that generates a disposition instruction and an associated access command directed to a block of data at a logical address is described. The disposition instruction and the access command are communicated to a memory system in the computer system via a communication link. Note that the memory system includes different types of memory having different performance characteristics, and the disposition instruction is generated based on the different performance characteristics. In response to the access command, the memory system accesses the block of data at the logical address in a first type of memory in the different types of memory. Furthermore, based on the disposition instruction, the memory system moves the block of data to a second type of memory in the different types of memory to facilitate subsequent accesses to the block of data.
