APPARATUS AND METHOD FOR READING DATA BASED ON A PROGRAM STATUS OF A NON-VOLATILE MEMORY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17965369 titled 'APPARATUS AND METHOD FOR READING DATA BASED ON A PROGRAM STATUS OF A NON-VOLATILE MEMORY DEVICE

Simplified Explanation

The abstract describes a memory device that includes a memory group with multiple memory cells, a control circuitry, and a page buffer circuit. The control circuitry reads both a first hard decision data entry and a first soft decision data entry from a specific memory cell. The page buffer circuit consists of multiple data latches to store the hard and soft decision data entries, as well as at least one cache latch to store one of these data entries transferred from the data latches.

  • The memory device has a memory group with multiple memory cells.
  • The control circuitry reads both hard and soft decision data entries from a specific memory cell.
  • The page buffer circuit includes data latches to store the hard and soft decision data entries.
  • The page buffer circuit also includes a cache latch to store one of the data entries transferred from the data latches.

Potential Applications

  • This memory device can be used in various electronic devices such as computers, smartphones, and tablets.
  • It can be utilized in data storage systems, improving the efficiency and reliability of memory operations.

Problems Solved

  • The memory device solves the problem of efficiently reading both hard and soft decision data entries from a memory cell.
  • It addresses the challenge of storing and transferring the data entries within the page buffer circuit.

Benefits

  • The memory device allows for simultaneous reading of hard and soft decision data entries, enhancing data retrieval speed.
  • It provides efficient storage and transfer of data entries within the page buffer circuit, optimizing memory operations.
  • The device improves the overall performance and reliability of memory systems.


Original Abstract Submitted

A memory device includes a memory group comprising plural memory cells, a control circuitry configured to read a first hard decision data entry and a first soft decision data entry together from a first memory cell among the plural memory cells, and a page buffer circuit, coupled to the first memory cell via a bit line. The page buffer circuit includes plural data latches configured to store the first hard decision data entry and the first soft decision data entry and at least one cache latch configured to store one of the first hard decision data entry and the first soft decision data entry which are transferred from the plural data latches.
