1. A method comprising: performing a memory read operation using a first read voltage level; detecting that the memory read operation has resulted in a memory read error; and in response to detecting the memory read error includes more than one incorrect bit: performing a higher read voltage memory read operation using a higher read voltage level higher than the first read voltage level; performing a lower read voltage memory read operation using a lower read voltage level lower than the first read voltage level; and selecting a revised read voltage level for subsequent memory read operations based on the performing the higher read voltage memory read operation and the performing the lower read voltage memory read operation, wherein the selecting the revised read voltage level for the subsequent memory read operations further comprises: in response to the memory read error occurring in response to using the higher read voltage level and occurring in response to using the lower read voltage level, increasing the higher read voltage level, decreasing the lower read voltage level, and reiterating the performing the higher read voltage memory read operation, the performing the lower read voltage memory read operation, and the selecting the revised read voltage level; and in response to the memory read error not occurring in response to using the higher read voltage level and not occurring in response to using the lower read voltage level, providing an indicator that a memory device has failed.
