APPARATUSES AND METHODS FOR SINGLE-PASS ACCESS OF ECC INFORMATION, METADATA INFORMATION OR COMBINATIONS THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240161856 titled 'APPARATUSES AND METHODS FOR SINGLE-PASS ACCESS OF ECC INFORMATION, METADATA INFORMATION OR COMBINATIONS THEREOF

Simplified Explanation

The patent application describes apparatuses, systems, and methods for single-pass access of ECC information, metadata information, or combinations thereof in a memory array. The memory array includes a number of column planes and an extra column plane. A memory device can be set in a 4x single-pass operational mode, where data is stored in selected column planes and metadata is stored in the extra column plane. An error correction code circuit (ECC) stores parity bits associated with the data and metadata in non-selected column planes, allowing for single access of the memory array to retrieve data, metadata, and parity.

  • Memory array with multiple column planes and an extra column plane
  • 4x single-pass operational mode for storing data and metadata
  • ECC circuit stores parity bits in non-selected column planes
  • Single access of memory array for data, metadata, and parity retrieval

Potential Applications

This technology could be applied in:

  • Data storage systems
  • Error correction systems
  • Metadata management systems

Problems Solved

This technology solves the following problems:

  • Efficient access to data, metadata, and parity information
  • Simplified memory array architecture
  • Streamlined error correction processes

Benefits

The benefits of this technology include:

  • Improved data retrieval efficiency
  • Enhanced error correction capabilities
  • Optimal use of memory array resources

Potential Commercial Applications

Potential commercial applications of this technology include:

  • Solid-state drives
  • Cloud storage systems
  • Data centers

Possible Prior Art

One possible prior art for this technology could be:

  • Memory arrays with separate storage for data and metadata

Unanswered Questions

1. How does this technology compare to traditional memory array architectures in terms of speed and efficiency? 2. Are there any limitations to the 4x single-pass operational mode in terms of scalability or compatibility with existing systems?


Original Abstract Submitted

apparatuses, systems, and methods for single-pass access of ecc information, metadata information, or combinations thereof. the memory array includes a number of column planes and an extra column plane. a memory device may be set in an �4 single-pass operational mode. in this mode, the memory may store data in a selected ones of the column planes, and metadata may be stored in the extra column plane. an error correction code circuit (ecc) may store parity bits associated with the data and metadata in non-selected ones of the column planes. in this manner, the data, metadata, and parity may be accessed as part of a single access of the memory array.
