Abstract
A memory apparatus and operating method are provided. The apparatus includes memory cells configured to retain a threshold voltage. A control means is configured to read the memory cells using a primary set of read level offsets and determine a value of an error metric for each of the primary set of read level offsets. The control means reads the memory cells using a secondary set of read level offsets based on the value of the error metric for each of the read level offsets of the primary set and determines the value of the error metric for each of the secondary set of read level offsets. The control means is also configured to read the memory cells at an optimum read level determined based on analysis of the value of the error metric for each of the read level offsets of both the primary set and the secondary set.
