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 18504342 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 with multiple column planes and an extra column plane. The memory device operates in a 4x4 single-pass operational mode, storing data in selected column planes and metadata in the extra column plane, while error correction code (ECC) circuit stores parity bits in non-selected column planes. This allows for the data, metadata, and parity to be accessed in a single access of the memory array.

  • Memory array with multiple column planes and an extra column plane
  • Memory device operating in a 4x4 single-pass operational mode
  • Data stored in selected column planes, metadata in the extra column plane, and parity bits in non-selected column planes
  • Single access of the memory array to retrieve data, metadata, and parity

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.
