BIT ERROR MANAGEMENT IN MEMORY DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18049121 titled 'BIT ERROR MANAGEMENT IN MEMORY DEVICES

Simplified Explanation

- This patent application describes a memory device that can read data stored in a non-volatile memory in a different format than it is stored. - The memory device uses an error correction circuit to compare multiple copies of the data and determine the most reliable bit state for each bit. - The memory device then stores the error-corrected data in the original format in the non-volatile memory. - When a read command is received, the memory device retrieves and returns the error-corrected data in the original format.

Original Abstract Submitted

In some implementations, a memory device may receive a command to read data in a first format from non-volatile memory, the data being stored in a second format in the non-volatile memory, the second format comprising a plurality of copies of the data in the first format. The memory device may compare, using an error correction circuit, the plurality of copies of the data to determine a dominant bit state for bits of the data. The memory device may store the dominant bit state for bits of the data in the non-volatile memory as error-corrected data in the first format. The memory device may cause the error-corrected data to be read from the non-volatile memory in the first format as a response to the command to read the data in the first format.
