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

An apparatus comprising:

• lines configured to transfer information that includes groups;
• and
• a module configured to:
• assign an identification to each of the groups in information;
• identify the identification of a specific group among groups if a single erroneous bit has occurred in the information and if the single erroneous bit belongs to the specific group;
• and
• prevent at least one of misidentifying and ignoring multiple-bit errors if the multiple-bit errors include a plurality of erroneous data bits that belong to the specific group and if none of the other groups of the plurality of groups have errors.

A system comprising:

• a controller;
• a memory device;
• and
• a module configured to transfer information between the memory device and the controller in plurality of transfers, the information including groups, each of the groups including bits and to implement a matrix that includes a first portion to enable detection of errors in a number of transfers among the plurality of transfers and a second portion to enable identifying whether the detected errors have occurred to bits of one of the groups.
