Systems and Methods for Choosing a Memory Block for the Storage of Data Based on a Frequency With Which the Data is Updated

摘要

Systems and methods for choosing a memory block for the storage of data based on a frequency with which data is updated are disclosed. In one implementation, a memory management module of a non-volatile memory system receives a request to open a free memory block for the storage of data. The memory management module determines a frequency with which the data is updated. The memory management module then opens a memory block of a first portion a free block list that is associated with low program/erase cycle counts in response to determining that the data will be frequently updated or opens a memory block of a second different portion of the free block list that is associated with high program/erase cycle counts in response to determining that the data is not frequently updated. The memory management module then stores the data in the open memory block of the non-volatile memory.

1. In a memory management module of a non-volatile memory system that is coupled with a host device, a method comprising:
receiving a request to open a free memory block of a non-volatile memory of the non-volatile memory system for the storage of data; determining a frequency with which the data is updated; opening a memory block of a first portion a free block list that is associated with low program/erase cycle counts in response to determining that the data will be frequently updated; opening a memory block of a second different portion of the free block list that is associated with high program/erase cycle counts in response to determining that the data is not frequently updated; and storing the data in the open memory block of the non-volatile memory.
