  • Storage device and method of operating the same
    Patent number: 11194510
    Abstract: A storage device and a method of operating a storage device including a non-volatile memory. The method includes selecting a first task from among a plurality of tasks queued in a task queue of the storage device; determining whether a mode of the first task is identical to a mode of a previously-executed task; and determining an execution order of the first task according to a result of determination. The modes and the region addresses of tasks may be utilized to group tasks to permit interleaving of programming data.

  • Method of dynamic garbage collection for a memory device based on valid page count (VPC), garbage collection speed, and maximum and minimum operating speeds
    Patent number: 10613975
    Abstract: A memory device and a dynamic garbage collection method thereof are provided. The method includes receiving a minimum operating speed, ascertaining a reference valid page count ratio (VPC), using a maximum operating speed, the minimum operating speed, and a garbage collection speed, the reference VPC ratio being ascertained by the following formula 1 and determining whether to perform a garbage collection, using the reference VPC ratio and a current average VPC ratio. <Formula 1> Vr=Gp (Jp?Mp)/(Jp*Mp+(Gp*(Jp?Mp))) Here, Vr is the reference VPC ratio, Gp is the garbage collection speed, Jp is the maximum operating speed, and Mp is the minimum operating speed.
