Setting a default read signal based on error correction

A method, comprising:

• reading data from a group of memory cells with a plurality of discrete read signals;
• counting a number of errors corrected for the data read with each of the plurality of discrete read signals;
• comparing the number of errors for each of the plurality of discrete read signals;
• and
• setting one of the plurality of discrete read signals as a default read signal based, at least in part, on the comparison.

A method, comprising:

• reading a page of user data from a group of memory cells with a first discrete read signal as part of a test operation of a memory apparatus;
• counting a number of errors corrected for the data as read with the first discrete read signal;
• reading the page of user data from the group of memory cells with a second discrete read signal as part of the test operation of the memory apparatus;
• counting a number of errors corrected for the data as read with the second discrete read signal;
• comparing the number of errors for each of the first discrete read signal and the second discrete read signal;
• and
• setting, during idle time of the memory apparatus, one of the first discrete read signal and the second discrete signal as a default read signal based, at least in part, on the comparison.

An apparatus, comprising:

• a memory array;
• and
• a controller coupled to the memory array, and configured to:
• read data from a group of memory cells with a plurality of discrete read signals;
• count a number of errors corrected for the data read with each of the plurality of discrete read signals that do not return an uncorrectable error;
• compare the number of errors for each of the plurality of discrete read signals;
• and
• set one of the plurality of discrete read signals as a default read signal based, at least in part, on the comparison.
