COMMAND PRIORITIZATION IN A COMMAND QUEUE

Abstract:

Devices and techniques for command prioritization in a command queue of a memory device are described herein. A command can be received at the memory device. An expiration time for the command can be obtained and the command can be placed into the command queue. Entries in the command queue are ordered by expiration times of commands stored therein, such that earlier entries are closer to the head of the command queue. When the memory controller is able to perform a command, the memory controller selects the next command at the head of the command queue to perform.
