Storage System and Method for Using a Queue Monitor in a Block Allocation Process - A simplified explanation of the abstract

This abstract first appeared for US patent application 17828285 titled 'Storage System and Method for Using a Queue Monitor in a Block Allocation Process

Simplified Explanation

The patent application describes a storage system with a memory that can store multiple bits per cell or only one bit per cell.

  • The storage system can choose to store only one bit per cell to improve performance.
  • However, this can reduce the endurance of the memory.
  • The storage system monitors a command queue to determine the required performance.
  • Based on this information, the storage system decides whether it is worth sacrificing endurance for increased performance.


Original Abstract Submitted

A storage system has a memory with a multi-level cell (MLC) block that can store multiple bits per cell or can be constrained to store only one bit per cell. Using the MLC block to store only one bit per cell can increase the performance of the storage system but can also reduce endurance of the MLC block. The storage system can monitor a command queue to determine the performance needed. With that information, the storage system can determine whether it is worth making the tradeoff of increasing performance at the cost of endurance.
