Setting a default read signal based on error correction

摘要

Apparatuses and methods related to setting a default read signal based on error correction include reading a page of data from a group of memory cells with a first discrete read signal and error correcting at least one codeword of the page of data as read with the first discrete read signal. Methods can include reading a page of data from the group of memory cells with a second discrete read signal different than the first discrete read signal and error correcting at least one codeword of the page of data as read with the second discrete read signal. One of the first and the second discrete read signals can be set as a default read signal based at least in part on the respective error corrections.

1. 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 during idle time of a memory apparatus; error correcting, as part of the test operation during idle time of the memory apparatus, at least one codeword of the page of user 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 different than the first discrete read signal as part of the test operation during idle time of the memory apparatus; error correcting, as part of the test operation during idle time of the memory apparatus, at least one codeword of the page of user data as read with the second discrete read signal; and setting, during idle time of the memory apparatus, one of the first and the second discrete read signals as a default read signal based at least in part on the respective error corrections.
