Abstract
Provided herein may be a storage device and a method of operating the same. A memory controller for controlling a memory device including a plurality of memory blocks having improved read performance may include a random read workload control unit configured to control a state of a random read workload such that the random read workload is in any one of a set state and a clear state depending on a random read count obtained by counting a number of random read requests that are inputted from an external host; and a random read processing unit configured to retrieve a physical address corresponding to a logical address of the respective random read requests depending on the state of the random read workload.
Claims20
A storage device, comprising:
- a buffer memory configured to temporally store data from a host;
- non-volatile memory chips;
- and
- a memory controller configured to control the buffer memory and the non-volatile memory chips to migrate the data from the buffer memory to the non-volatile memory chips based on a number of random read request from the host.
A memory controller comprising:
- a random read workload control unit configured to control a state of a random read workload in any one of a set state and a clear state depending on a random read count obtained by counting a number of random read requests inputted from an external host;
- and
- a read processing unit configured to retrieve a physical address corresponding to a logical address of a read request depending on the state of the random read workload.
