Extended single-bit error correction and multi-bit error detection

Abstract

Some embodiments include a method for when a multi-bit error includes a plurality of erroneous data bits belonging to only one specific group of the plurality of groups of data bits and none of the other groups of the plurality of groups have Apparatus and method for preventing misidentification of said multi-bit error and ignoring at least one case of said multi-bit error in case of error.

Description

[0001] Related Application Cross Reference [0002] This patent application claims the benefit of priority to US Application Serial No. 12 / 417,390, filed April 2, 2009, which is incorporated herein by reference. technical field Background technique [0003] Data and other information used in computer systems and various electronic devices typically consists of many pieces of information called bits. Each bit has a value such as binary 0 or binary 1. In some cases, factors such as physical defects, cosmic rays, and improper use can alter the value of a single bit or the value of multiple bits of data information stored in these systems or devices. Therefore, erroneous data information may appear in some situations. Many conventional systems or devices may include error detection and correction components to detect and correct certain errors in data information. For example, some systems have components to correct single erroneous bits of data information. However, even w...
