Methods of accessing memory cells, methods of distributing memory requests, systems, and memory controllers

摘要

Methods of accessing memory cells, methods of distributing memory requests, systems, and memory controllers are described. In one such method, where memory cells are divided into at least a first region of memory cells and a second region of memory cells, memory cells in the first region are accessed according to a first address definition and memory cells in the second region are accessed according to a second address definition that is different from the first address definition. Additional embodiments are described.

主权项

1. A system comprising:
a pre-decode block to:
receive a request address associated with a memory request corresponding to memory cells in a memory system;rearrange the request address into a first memory address according to a first definition if the request address corresponds to memory cells in a first region of the memory system; andcomparing a size of the request address to a channel depth of the region to which the request address is directed, wherein the channel depth comprises a number of bytes to be accessed from the channel before the request address moves to another channel;rearrange the request address into a second memory address according to a second definition if the request address corresponds to memory cells in a second region of the memory system, the second definition being different from the first definition; and a memory controller configured to receive the first or the second memory address and to execute at least a portion of the memory request in the memory system.
