1. A memory controller, comprising:
- a plurality of back end channels, each back end channel corresponding to a different memory device; and
a front end command dispatcher communicatively coupled to the plurality of back end channels and a command queue configured to hold a number of read commands,wherein the front end command dispatcher is configured to determine a net read from memory to be accomplished by the number of read commands, and to modify one or more of the number of read commands such that fewer commands are sent to accomplish the same net read from memory in order to economize distribution of the number of read commands among the plurality of back end channels.

Abstract
The present disclosure includes methods and devices for a memory controller. In one or more embodiments, a memory controller includes a plurality of back end channels, and a command queue communicatively coupled to the plurality of back end channels. The command queue is configured to hold host commands received from a host. Circuitry is configured to generate a number of back end commands at least in response to a number of the host commands in the command queue, and distribute the number of back end commands to a number of the plurality of back end channels.

6. A memory controller, comprising:
-
a plurality of back end channels, each back end channel corresponding to a different memory device; and a front end command dispatcher communicatively coupled to the plurality of back end channels and a command queue configured to hold a number of write commands, wherein the front end command dispatcher is configured to determine a net change to memory to be accomplished by the number of write commands, and to modify one or more of the number of write commands such that fewer commands are sent to accomplish the same net change to the memory in order to economize distribution of the number of write commands among the plurality of back end channels. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
