Systems and Methods for Performing an Adaptive Sustain Write in a Memory System

摘要

Systems and methods for performing an adaptive sustain write are disclosed. In one implementation, a controller of a non-volatile memory that is coupled with a host system monitors a rate at which the host system sends user data to the non-volatile memory system for storage and determines that the rate at which the host system sends user data to the non-volatile memory system for storage exceeds a threshold. The controller stores a first portion of the user data in one or more user capacity memory blocks of the non-volatile memory system. Additionally, the controller stores a second portion of the user data in one or more over-provisioning memory blocks of the non-volatile memory system after determining that the rate at which the host system sends data to the non-volatile memory system for storage exceeds the threshold.

1. In a controller of a non-volatile memory system that is coupled to a host system, a method comprising:
monitoring a rate at which the host system sends user data to the non-volatile memory system for storage; determining that the rate at which the host system sends user data to the non-volatile memory system for storage exceeds a threshold; storing a first portion of the user data from the host system in one or more user capacity memory blocks of the non-volatile memory system; and storing a second portion of the user data from the host system in one or more over-provisioning memory blocks of the non-volatile memory system after determining that the rate at which the host system sends data to the non-volatile memory system for storage exceeds the threshold.
