Abstract
Provided herein may be a memory controller and a method of operating the same. The memory controller may control a memory device in response to a command received from a host. The memory controller may include a write amplification factor (WAF) storage and a standby state controller. The WAF storage may store a WAF of the memory device. The standby state controller may control entry of the memory controller into a standby state based on a value of the WAF stored in the WAF storage.
Claims16
A memory controller for controlling a memory device in response to a command received from a host, the memory controller comprising:
- a write amplification factor (WAF) storage configured to store a WAF of the memory device;
- and
- a standby state controller configured to control entry of the memory controller into a standby state based on a value of the WAF stored in the WAF storage.
A method of operating a memory controller, the memory controller controlling an operation of a memory system including at least one memory device, the method comprising:
- determining a write amplification factor (WAF) of the memory system;
- comparing a value of the WAF with a standby-prevention threshold value;
- and
- controlling entry of the memory system into a standby state based on a result of the comparison.
A memory system comprising:
- a memory device;
- and
- a memory controller configured to control the memory device,
- wherein the memory controller:
- detects a write amplification factor of the memory device;
- and
- controls a frequency or number of times the memory system is permitted to transition from an operation state to a standby state based on the write amplification factor.
