SYSTEMS AND METHODS FOR ACCESSING MEMORY

摘要

Methods of mapping memory cells to applications, methods of accessing memory cells, systems, and memory controllers are described. In some embodiments, a memory system including multiple physical channels is mapped into regions, such that any region spans each physical channel of the memory system. Applications are allocated memory in the regions, and performance and power requirements of the applications are associated with the regions. Additional methods and systems are also described.

1. A method for accessing a memory system, the memory system including two or more physical channels, the method comprising:
receiving a request for access, the request including a logical memory address; retrieving a channel depth associated with a region of the memory system that corresponds to the logical memory address, each region of the memory system distributed across the two or more physical channels to include at least a respective portion of each of the two or more physical channels, the respective portions being located at a same position within each of the two or more physical channels; and performing an operation on the memory system in the region corresponding to the logical memory address, based on the retrieved channel depth and based on the request for access.
